In other words over coating layer (660) is also shown in the bank layer 3 (336) opening (336a) includes a plurality of protrusions arranged to be overlapping (663) on a projection (663) each connecting the plurality of connection number 2 (664) without using a tool.

Over-coating layer (660) number 1 on electrode (641) disposed thereon. Over-coating layer (660) and number 1 electrode (641) layer on a (637) is disposed, electrode number 1 (641) and pattern layer (637) on the organic light emitting layer (642) and number 2 electrode (643) disposed thereon. Number 1 electrode (641) of an organic light emitting layer (642), number 2 electrode (643) the organic (640) constituting other. Pattern layer (637) includes a plurality of number 2 connection (664) all or a portion can be located.

Pattern layer (637) connecting a plurality of number 2 (664) all or a portion placed, also described with reference to the pattern layer also 1 to 8 (337) in the recess (361) located equal, is number 1 electrode of the non-effective light emitting region (641) of an organic light emitting layer (642) and number 2 electrode (642) between the pattern layer (637) rotates the planar light is not, light extraction efficiency in the luminescence area proportion which contributes to improvement which does not nearly organic light-emitting device (640) minimizing or preventing the entrapped within the can. In addition proportion (B) light emitting region of the organic light-emitting device (640) entrapped within the common component minimizing or preventing the light is left in a can. Through organic light-emitting device (640) can be downloaded from the external light extraction efficiency.

Figure 10 shows a schematic diagram of the organic light emitting display device according to the invention in the embodiment a system configuration are disclosed.

10 Also reference surface, the organic light emitting display device in the embodiment according to the (700) includes, a plurality of data line (DL) (GL) is disposed and a plurality of gate lines, a plurality of subpixel (SP) arranged in a matrix type organic light emitting display panel (710) and, by supplying a plurality of data line driver outputs a plurality of data line driver (720) on, sequentially supplies scan signal by a plurality of gate lines, a plurality of gate line and the gate driver sequentially (730) on, data driver (720) and a gate driver (730) a number plower controller (740) etc..

The organic light emitting display panel are in the embodiment according to (710) each have a plurality of pixels disposed, described with reference to organic light emitting thin film transistor and also 1 to 9 also includes.

In the embodiment according to the aforementioned, organic light emitting display device comprises an outer light emitting efficiency, power consumption may be equal to or less than.

In addition to the aforementioned in the embodiment according, organic light emitting display device while the inside of the over coating layer comprises an outer light emitting efficiency is improved at a second curvilinear shapes can be maintained equal to or less than.

A feature of the present invention illustratively attached described and more provided revealing the secret key are in the drawing, the present invention essentially from deviating from a person with skill in the art in the field of the present invention is provided if the properties of inputted configuration, separation, a variety of modifications and deformable substitution and change will. Thus, the present invention in the embodiment of the present invention are to define the disclosure but rather to explain the feature and, in the embodiment of the present invention by not the limited range of such feature. Under the protection range of the present invention must be interpreted by fee so as to range, and the range of the present invention feature in a range equal to all rights will be interpreted.
