Liquid crystal display with optical compensation

Abstract

A liquid crystal display includes a first substrate, a second substrate, a liquid crystal layer, a first phase compensation plate, a second phase compensation plate, an optical compensation film, a first polarizer and a second polarizer. The liquid crystals of the liquid crystal layer are arranged in an optically compensated bend mode. The first phase compensation plate is located outside the first substrate. The second phase compensation plate is located outside the second substrate. The first phase compensation plate and the second phase compensation plate include layers of discotic liquid crystal in order to reduce the dark-state leakage of the liquid crystal layer. The optically compensated film may include a single-axis extension retardation plate (“A-plate”) located outside the first phase compensation plate in order to reduce the oblique leakage of the polarizers extending perpendicular to each other. The phase compensation plate and the optically compensated film reduce the dark-state leakage and the oblique leakage of the optically compensated bend mode display in order to increase the contrast and view angle of the liquid crystal display.
