ABSTRACT:
A liquid crystal display device comprising a liquid crystal display in which polarizing plates A and B are provided so as to be held between a vertical orientation mode crystal cell and the corresponding liquid crystal cell, wherein the polarizing layer A comprises the polarizing plate protective films A1and A2and the polarizing layer B comprises the polarizing plate protective films B1and B2, and at least one of the polarizing plate protective films A2and B2that are disposed at the liquid crystal cell side is a cellulose ester film Y that simultaneously satisfies the condition that retardation value Ro is 0 to 10 nm and Rt is −20 to 20 nm shown by the equation below, and at least one of the polarizing plate protective films A2and B2is the optical compensation film W which has an optically anisotropic layer.
