Abstract:
1. A polarizing plate comprising: a polarizing film; and two transparent protective films, wherein the polarizing film is between the two transparent protective films, and at least one of the two transparent protective films is an optical compensatory sheet comprising a cellulose acylate film, wherein the polarizing plate has a polarization degree P calculated by formula (1) of more than 99.95%, and when two of the polarizing plates are arranged in a cross nicol configuration, the two polarizing plates have a transmittance at 700 nm of 0.07% or less and a transmittance at 410 nm of 0.05% or less: wherein H0 represents a transmittance of two of the polarizing plates at the time the two polarizing plates are stacked on each other such that absorption axes of the two polarizing plates correspond with each other; and H1 represents a transmittance of two of the polarizing plates at the time the two polarizing plates are stacked on each other such that the absorption axes of the two polarizing plates are perpendicular to each other, and wherein hue x, y in a CIE color space, when two of the polarizing plates are arranged in a cross nicol configuration, satisfy 0.28≦x≦0.30 and 0.28≦y≦0.30.
