发明名称 LIQUID CRYSTAL DISPLAY
摘要 <p>A liquid crystal display comprising a liquid crystal cell in a homeotropic alignment mode, and polarizing plates A and B sandwiching the liquid crystal cell. This liquid crystal display is characterized in that the polarizing plate A has polarizing plate protective films A1 and A2, the polarizing plate B has polarizing plate protective films B1 and B2, at least one of the polarizing plate protective films A2 and B2 arranged on the liquid crystal cell side includes a cellulose ester film Y satisfying a requirement that the in-plane retardation value Ro represented by the expression below is 0-10 nm and a requirement that the retardation value Rt in the film thickness direction is -20 to 20 nm at the same time, and at least one of A2 and B2 is an optical compensation film W having an optically anisotropic layer. The liquid crystal display is suppressed in chromatic variation even if the environment varies, and it is also suppressed in color variation even if the angle is varied during appreciation. The liquid crystal display exhibits high contrast while suppressing variation in visibility due to drawing speckle. Expression (a): Ro=(nx-ny)×d Expression (b): Rt=((nx+ny)/2-nz)×d</p>
