Optical film |
| abstract |
An optical film having a desired wavelength dispersion characteristic, a low photoelastic coefficient and a desired Nz coefficient. n The optical film is formed from a copolymer and meets the following conditions (i) to (v): n(i) the thickness (d) is 20 to 80 µm; n(ii) the following formulas (1) and (2) are satisfied: 0.6 < R 450 / R 550 < 1 1.01 < R 650 / R 550 < 1.40 n(R(450), R(550) and R(650) are retardations within the plane of the film at respective wavelengths); n(iii) R(550) is 120 to 160 nm; n(iv) the birefringence (Δn) is not less than 1.5 x 10 -3 ; and n(v) the Nz coefficient represented by the following formula. (4) is 1.18 to 2.40: Nz = n x - n z / n x - n y n(n x , n y and n z are 3-dimensional birefringences of the film). |
