<P>PROBLEM TO BE SOLVED: To provide an optical film formed by laminating an absorption type polarizer and a birefringent film, the optical film being characterized in that a high contrast is obtained at a wide field angle with high transmissivity and high polarization degree being secured and unevenness of transmissivity during black display can be suppressed. <P>SOLUTION: The optical film has a transparent film which is formed of a scatter-dichroic absorption composite type polarizer formed of a film in structure such that fine regions are dispersed in a matrix formed of translucent resin containing an iodine-based light absorber and a solid polymer, the birefringent film satisfying nx>ny>nz, where nx, ny, and nz are refractive indexes in directions of an X axis where an in-surface refractive index becomes maximum, a Y axis perpendicular to the X axis, and a Z axis along the thickness of the film. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
