Patent ID: 8310633

Claim:
A liquid crystal display, comprising: a liquid crystal display panel having a vertical alignment liquid crystal layer; a first polarizer and a second polarizer respectively disposed at two sides of the liquid crystal display panel; a first a-plate and a second a-plate, wherein the first a-plate is disposed between the liquid crystal display panel and the first polarizer, and the second a-plate is disposed between the liquid crystal display panel and the second polarizer; a biaxial retardation plate disposed between the first a-plate and the first polarizer or disposed between the second a-plate and the second polarizer, wherein the biaxial retardation plate has a plurality of main axis refractive indexes n x , n y and n z , and the main axis refractive indexes n x , n y and n z satisfy the formula: Nz =( n x −n z )/( n x −n y ) wherein n x >n y , and −0.5<Nz<1; and a first c-plate disposed between the liquid crystal display panel and the first a-plate or disposed between the liquid crystal display panel and the second a-plate.
