Abstract:
A liquid crystal display includes: a liquid crystal layer squeezed between first and second transparent substrates and vertically aligned at a retardation of 300 nm or larger to 940 nm or smaller; two or three viewing angle compensators disposed on the first transparent substrate on the side opposite to the liquid crystal layer, each of the viewing angle compensators having a retardation of 90 nm or larger to 350 nm or smaller in a thickness direction and a retardation of 5 nm or larger to 30 nm or smaller in an in-plane direction; a first polarizer disposed on the two or three viewing angle compensator; and a second polarizer disposed on the second transparent substrate and crossed-Nichol disposed relative to the first polarizer, wherein an in-plane slow axis of each viewing angle compensator is disposed perpendicular to an absorption axis of the first polarizer.
