<P>PROBLEM TO BE SOLVED: To provide an optical film capable of suppressing light unevenness and improving the contrast ratio of a liquid crystal display device. <P>SOLUTION: The optical film includes cellulose ester and an acrylic resin. The mass ratio of the cellulose ester to the acrylic resin is 70/30 to 5/95, the total haze value of the optical film is 0.80 or smaller, the internal haze value of the optical film is 0.01 to 0.28, and the modulus of elasticity in the transverse direction of the optical film is 2,700 to 7,000 MPa. <P>COPYRIGHT: (C)2011,JPO&INPIT |
