Abstract:
A vertical alignment type liquid crystal display, which has a liquid crystal layer whose retardation value is about 600 nm or more, can solve the viewing angle problems associated with the wider viewing angle. The liquid crystal display can include a vertical alignment liquid crystal cell, and first and second polarizing plates cross-Nicol disposed on respective sides of the liquid crystal cell. The liquid crystal cell has a liquid crystal layer with a retardation of about 600 nm or more. A biaxial plate is provided between the liquid crystal cell and the first polarizing plate, and two C-plates are provided between the liquid crystal cell and the second polarizing plate.
