摘要： PROBLEM TO BE SOLVED: To provide a polarizing plate that hardly causes coloring due to a variation of a wavelength, has a high neutral property, and hardly causes a light leak even if a polarizer arranged in a crossed Nichol prism is obliquely viewed from an azimuth shifted from an optical axis. SOLUTION: In the polarizing plate, a transparent protective film (2) composed of a two-layer phase difference film (21 and 22) where an in-plane phase difference by light with a wavelength of 550 nm is 190-320 nm is stuck to at least one side of the polarizer (1) so that the delay phase axis of each phase difference film has a parallel relation with the absorption axis of the polarizer. When nx>ny and Nz=(nx-nz)/(nx-ny) where the refractive index in the surface is denoted with nx and ny and the refractive index of the thickness direction is denoted with nz, the two-layer phase difference film is formed of a combination of a film of 0.8-0.95 and a film of 0.55-0.7 based on the Nz. The compensatory action of canceling the change of the optical axis such as the absorption axis of the polarizer is obtained by changing the optical axis such as the delay phase axis of the phase difference film forming the transparent protective film correspondingly to the change of the viewing angle.
