And moist heat (高 濕熱) may decrease the degree of polarization under the environment, the color change and the light polarizing plate and a liquid crystal display device leakage does not substantially take place, are disclosed. The polarizing plate of the present invention is a temperature 80 ℃ and RH 90% atmosphere under 24 sigan left one after the polarization degree retention ratio is 0.97 or more, the luminance sustain ratio is 3.0 or less, the absolute value of the amount of change in a value by haenteo Lab method is 0.6 or less, the absolute value of the amount of change in the b value of 1.0 or less includes a polyvinyl alcohol polarizing film. Further, the polarizing plate is bonded to the liquid crystal display of the present invention. A polarizing plate, a liquid crystal display device, liquid crystal display devices, in-plane retardation, the protective film
