In a small number of optical film 109, cycloolefin resin types, number web surfing with retardation rise amount, general formula (1) having a structure represented by an exemplary compound to odd pixels of an add-on, addition has identically to each film thickness changing, optical film 110 to a small number-gate 129.

≫ ≪ evaluation

Number 101 to 129 to work grudge optical film, a method of embodiment hereinafter was evaluated.

(1) Non-uniform phase difference

Each optical film width of 50 mm in a direction to 10 point sampling intervals, of Ro (optical wavelength 550 nm) was measured phase procedure to price.

The entire measurement [...][...] as non-uniform phase difference difference, to the criteria was assessed.

A: less than 1 nm retardation unevenness

B: less than 2 nm 1 nm or more retardation unevenness

C: less than 4 nm 2 nm or more retardation unevenness

D: 4 nm or more retardation unevenness less than 6 nm

E: retardation unevenness 6 nm or more

Wherein, free C level is greater than the practical door number, preferably B level, more preferably A level.

(Measurement of phase price Ro)

It is 55% RH environment in optical wavelength 550 nm retardation in plane of Ro 23 °C [...] exhibits.

Ro is, in light of wavelength 550 nm (small [kkwu gating on the meal (main) number) KOBRA 21ADH film to a direction normal to the incident were measured. The value of the Abbe to average refractive index readings were measured. These average refractive index film thickness value by inputting a hypothesis, KOBRA 21ADH is n_x , N_y , N_z Formula (i) calculated based on phase price Ro related to HRV.

Type (i): Ro=(n_x - N_y ) × d (nm)

(A coloring composition, is d, exhibits optical thickness of a film (nm). n_x Is, an in-film (terrestrial axis) represents the maximum refractive index, n_y Is, the refractive index in the direction perpendicular to the axis in the film plane exhibits.)

(2) A defective appearance (wrinkles, sagging)

In the process of production, lot 10 inclination of visually observing the appearance and stretch of film, a degree of occurrence of wrinkles was assessed by the standards of user inserts hereinafter.

◎: 10 lot both user inserts wrinkles that is free from disclosed

○: 9 in which the lot for user inserts an expansive, lot remaining 1 generation of user inserts wrinkles mild disclosed

Δ: 6 in which the lot for user inserts an expansive, lot of wrinkles cannot be mixed during the remaining 4 user inserts his practical level

×: 4 in which the lot for user inserts an expansive, the user inserts the remaining 6 lot practical level cannot be wrinkles are disclosed

Table 1 exhibits the estimation result.

From table 1, the constitution of the invention the optical film has, excellent retardation unevenness, in addition (wrinkles, sagging) characterized by a generation of a defective appearance can be known.

In the embodiment 2

In the embodiment 1 in a small number of optical film 109, instead of example compound 1 by the general formula (1) compound having a structure represented by 3, 8 and 9 of the present invention other than by the same heating of illustrative compounds that can prepare the small number and optical film, at which a phase difference of irregularity in the evaluation in the embodiment 1, optical film 109 and reproduce the result of, retardation unevenness has been found excellent results were achieved.

Example compound 3: [...] 171 (BASF re-fan (main) number)

Example compound 8: [...] 479 (BASF re-fan (main) number)

Example compound 9: [...] 460 (BASF re-fan (main) number)

In the embodiment 3

(Circular polarization petal small number)

Number using work grudge optical film 101 to 129, 129 [...] 101 becomes a smaller number to a hereinafter-gate.

80 Micro m iodine in aqueous solutions of polyvinyl alcohol film roll diameter thickness continuously 5 times stretching, drying of polarizers thicknesses on the order of 20 micro m are obtained. Bonding acrylic pressure-sensitive adhesive number by number, work grudge number in a ground axis of each optical film in the embodiment 1, so absorption polarizer 45°, joined using adhesive number and, on the other side polarizer protective film ([...][...] tack KC4UY, thickness 40 micro m, [...][...] (main) number) joined by a [...], small circular polarization petal number-gate.

(Organic EL cell small number)

3 Mm thickness of 50 inches (127 cm) for alkali-free glass, the method described in the embodiment of Japanese patent disclosure number 2010 - 20925 call Official Gazette and satisfying, also including a small organic EL cell number 8 Official Gazette of Japanese patent disclosure number 2010 - 20925 call-gate configuration.

(Small number of display device)

Said work grudge number in each circular polarization petal number after a coating adhered to the surface of optical film (λ / 4 retardation film), a small number-gate organic EL display device numbers of the liquid crystal cell.

Evaluation of ≫ ≪ display device

Work grudge said number with respect to respective display device, according to the [...], a signal color characteristics, such as reflective (visibility) basic display panel was assessed.

(1) Color nonuniformity

55% RH-like environment in the entire display and black display 23 °C, front and slope angle of from 45° monitoring, optical film was assessed with reference to non-uniformity of color due to non-uniform phase difference.

A: color nonuniformity is not observed

B: 1/8 hereinafter been weak in a display plane of the area of an external color nonuniformity

C: 1/8 1/4 hereinafter in greater than a weak area in a display plane of the been an external color nonuniformity

D: exceeds a weak area in a display plane of the 1/4 been an external color nonuniformity

E: exceeds an external area in a display plane of the 1/4 been strong color nonuniformity

Wherein, if the wait but practical door number C level, preferably B level and, in particular preferably greater than the A level.

(2) Visibility

A display device viewed visually from the front side of a reflective (visibility) was assessed.

◎: good reflective circular polarization petal, etc. and has good visibility is superior in black representation

○: but is preferably circular polarization petal reflective, low contrast slightly black expression appear other

Δ: circular polarization petal reflective slightly long, low contrast black expression appear other

×: circular polarization petal reflective long, black representation it is apparent that light source and is lower disclosed

Wherein, if the wait number ○ practical door level and, in particular preferably ◎ level or higher and the substrate.

From the results of table 2, using the optical film of the present invention to work grudge device is parallel to the circular polarization petal number, color nonuniformity and visibility is excellent in all can be boosted.
