In this embodiment, the bending direction to 1st is S1 and the 1st direction D1 between the angle of θ 1 is about 15 degrees, for example, but this invention does not limited to this, the bending direction of the 1st S1 and 1st direction D1 between the angle of θ 1 can also be as shown in Figure 2A to fig. 2C illustrated is about 45 degrees, or, bending direction 1st S1 and 1st direction D1 between the angle of θ 1 can also be as shown in Figure 3A to fig. 3C illustrated is about 90 degrees. In other words, as defined in the above, 1st direction D1 can be far away from the virtual parting line ml and 1st bending direction S1 is, for example, parallel or towards the virtual parting line ml. Furthermore, in the above-mentioned embodiment, in order to branch and is defined by the angle between the direction of θ 1, the fixation and 2, the fixation and 3, the 4 (2nd bending direction S2 and 2nd direction D2 between the angle θ 2, 3rd bending direction S3 and 3rd direction D3 of the angle between θ 3, 4th bending direction S4 and 4th direction D4 between the angle of θ 4) are the same as an example, but the invention is also not limited to this. In other words, to each branch can be performed according to requirements, with the definition of the direction of adjustment of the angle between the. In another embodiment, direction 1st D1 to be directed toward virtual parting line ml and 1st bending direction S1 parallel to or far away from the virtual parting line ml, for example, in the aforesaid embodiment of the configuration of the shared electrode, as a pixel electrode, the pixel electrode and as the configuration of the shared electrode, can be obtained so that the pixel electrode having the aforementioned relations. In other words, the technology of the present invention is characterized in that the virtual line direction 1st 1st bending, and a direction parallel to or away from the virtual parting line, or, far away from the virtual parting line and direction 1st 1st bending direction parallel to or towards the virtual parting line. In one embodiment (not draws shows), when the 1st branch and the 3rd branch is located in the lower part of the pixel region, the tail end part of the 1st bending upward direction 1st, 3rd 3rd end part is formed by bending downward direction, a branch and 2nd 4th branch is located in the upper part of the pixel region, the tail end part of the 2nd downwards direction 2nd, 4th 4th direction by the distal end portion is bent upward.

It is worth mentioning that, although in the above-mentioned embodiment of the pattern with the picture element electrode is 1A to fig. 3C the configuration of the shown, map and 1A to fig. 3C of the pixel electrode shown in the connection mode of the active element as an example, but the invention is not limited to this. In other words, in other embodiments, as long as the 1st branch of the other end part of the extension part of the definition of the direction and 1st the 1st bending direction of the virtual line can have a particular relationship, that is towards the virtual parting line and direction of 1st 1st bending direction parallel to or away from the virtual parting line, or, far away from the virtual parting line and direction 1st 1st bending direction parallel to or towards the virtual parting line, but not the picture element electrode configuration or the remaining component of the connection way of restrictions or configuration. Furthermore, according to the demand, the branch can be adjusted at will with the end part of the definition of the angle between the direction, and detachably connected between the length of the interval (pitch) of the distal end portion.

Figure 4 the draws shows one embodiment of the present invention of a schematic diagram of the pixel array layer is conducted. Please refer to fig. 4, the pixel array layer 210 comprises an array disposed on base plate 200 on the structure of a plurality of pixels 100, pixel structure 100 can reference the previous embodiment the, in this do not repeat. Pixel array layer 210 may be in-plane-switching type pixel array layer.

Figure 5 draws shows to one embodiment of the present invention of the liquid crystal display section of a schematic diagram. Requests with reference to Figure 5, the liquid crystal display 300 including map 4 array of pixels shown in the layer 200, color filter layer 220, liquid crystal alignment layer 230 and 240. Pixel array layer 200 include disposing in the base plate 210 the structure of a plurality of pixels 100. The liquid crystal layer 230 is disposed on the pixel array layer 200 with the color filter layer 220 between. The alignment layer 240 is disposed on the pixel array layer 200 and a liquid crystal layer 230 between, Da with an alignment direction, wherein the previous embodiment the 1st direction of D1 and mix to the direction Da does not substantially parallel, that is, 1st direction D1 between the alignment direction has an angle Da. In this embodiment, the liquid crystal display 300 is, for example, in-plane-switching type display. Of course, in this embodiment is in Figure 5 shown in the liquid crystal display 300 as an example, but in other embodiment, the liquid crystal display 300 can have also well known in the field of other configuration, in the do not repeat.

In the above-mentioned embodiment, the picture element electrode of the branch is designed to be with a bent end, the branch and with the extended portion at the end portion of the the direction of the other defined have a particular relationship between the virtual line. In this way, the generation of dark line can be reduced, in order to promote the efficiency of the liquid crystal, by adopting the pixel structure of the liquid crystal display is provided with a good penetration rate and the display quality.

Next, experiment example and the comparative example of the pixel structure of the present invention liquid crystal display is provided with a better liquid crystal benefits. Figure 6A with diagram 6B respectively the experimental example for comparison example of the Image analysis result of the pixel structure, wherein empty frame part of the area of the Image analysis. Figure 6C is relationship graph of comparative example and experimental example of the pixel structure with the position between the Image intensity. As shown in Figure the pixel structure has of experiment example 1A the structure of the shown, the branch of the 1st 1st 1st far away from the virtual parting line and the direction of bending of the virtual separation line parallel to the direction. Pixel structure of comparison example with diagram 1A substantially the same as the structure shown in, is characterized in that the main different branch 1st 1st 1st far away from the virtual parting line and the direction of the bending direction is also far away from the virtual parting line. Please also with reference to Figure 6A to fig. 6C, after the calculation, the average Image intensity of the comparative example for 111.53, the average Image intensity of experiment example 116.79. In other words, pixel structure of this invention the compares Yu Xizhi pixel structure, is added to the liquid crystal is 4.7%.

To sum up, in the pixel structure of this invention, the end part of the branch with the extended portion in the direction of the other defined have a particular relationship between the virtual line, in order to reduce the generation of dark lines. Therefore, liquid crystal efficiency can be improved, by adopting the pixel structure of the liquid crystal display is provided with a good penetration rate and the display quality. Furthermore, the pixel structure of this invention comprising the same and liquid crystal display in the pixel structure with known substantially the same as the liquid crystal display device, therefore, will not materially increase its cost of manufacture, and the pixel structure which greatly increases the yield and efficiency of the liquid crystal display. Furthermore, this invention is suitable for the manufacture of large-area liquid crystal display, such as in-plane switching liquid crystal display device.

Of course, the invention can also have other various embodiments, without departing from the invention spirit and its real circumstances, the technical personnel familiar with the field according to the present invention can be various corresponding change and deformation, but these relative changes and deformation of the invention should have the scope of protection of the claim.
