Patent ID: 7671937

Claim:
A polarizing plate comprising (a) a plurality of polyvinyl alcohol fibers adsorbing a dichroic pigment and having an aspect ratio of 10 or more, which are arranged in a planar form in one direction, (b) a plurality of fibers having an aspect ratio of 10 or more and a difference between the refractive index of fiber in long axis and the refractive index of fiber in short axis of 0.05 or more and not adsorbing a dichroic pigment, which are arranged in a planar form in one direction, and (c) an optically transparent resin, wherein the one direction where the plurality of fibers (a) are arranged and the one direction where the plurality of fibers (b) are arranged are the same or orthogonal to each other, when they are the same, the refractive index of fiber in short axis of the plurality of fibers (b) and the refractive index of the optically transparent resin (c) become almost the same and when they are orthogonal to each other, the refractive index of fiber in long axis of the plurality of fibers (b) and the refractive index of the optically transparent resin (c) become almost the same.
