PURPOSE:To obtain the polarizing plate which is applicable without substantially spoiling the high contrast of a liquid crystal cell. CONSTITUTION:The polarizing plate 4 is formed by laminating a polarizing plate (4) which has a transparent protection layer (1) on at least one side of a polarizing film (2), has >=35% visible light transmissivity, and the degree of polarization P satisfies P=sq. rt. (Tp-Tc)/(Tp+Tc)>=0.990 (where Tp is parallel transmissivity and Tc is orthogonal transmissivity) while the size variation rate at the time of 80 deg.C heating is <=0.3% and a polarizing plate 4 formed by laminating at least one phase difference film on one side of the polarizing plate, and the liquid crystal display device is constituted by arranging the polarizing plate 4 on at least one side of a liquid crystal cell. Therefore, the polarizing plate 4 which is superior in thermal stability enough to prevent the disorder of polarized light due to heat, maintains the polarizing characteristics of the polarizing film 2 at high level, and has the high degree of polarization is obtained and the liquid crystal display device which has the superior contrast and superior visual angle characteristics is obtained. |
