<P>PROBLEM TO BE SOLVED: To provide an optical film having a patterned optical anisotropic layer capable of reducing crosstalk when incorporated into a stereoscopic image display device. <P>SOLUTION: An optical film includes a pattern optical anisotropic layer 10 having a first retardation region 1 and a second retardation region 2. The first retardation region and the second retardation region are alternately arranged in the same plane, and are different from at least one of an in-plane slow axis direction and in-plane retardation. And a distance L between two adjacent boundaries among boundaries 3 between the first retardation regions and the second retardation regions is 1 mm to 50 mm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
