<P>PROBLEM TO BE SOLVED: To provide a polarizing plate superior in characteristics of optical compensation, small in change of polarization performance with time and superior in moisture and heat resistance, and to provide a liquid crystal display of a VA (vertically aligned) mode having a wide-viewing angle and little decrease in contrast over time passage. <P>SOLUTION: The polarizing plate comprises a polarizing film and two transparent protective films provided one on both sides of the polarizing film, in which at least one of the two protective films is an optical compensatory sheet comprising a cellulose acrylate film. The polarizing plate has specified single-plate transmittance and polarization degree P and has specified ranges of variations of the transmittance and the polarization degree, after the lapse of a specified period of time under a high-temperature, high-humidity atmosphere and a high-temperature, low-humidity atmosphere. The liquid crystal display device of a VA mode that uses the polarizing plate is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
