Patent ID: 8582061

Claim:
An optical film assembly comprising: a first polarization plate disposed below a liquid crystal layer and having a first absorption axis; a second polarization plate disposed above the liquid crystal layer and having a second absorption axis substantially perpendicular to the first absorption axis; an A-plate disposed between the first polarization plate and the second polarization plate; and a negative C-plate disposed between the first polarization plate and the second polarization plate, wherein a thickness-direction phase retardation value of the negative C-plate is equal to or less than a value acquired by subtracting about 75 nanometers from a thickness-direction phase retardation value of the liquid crystal layer, and the thickness-direction phase retardation value of the negative C-plate is equal to or greater than a value acquired by subtracting about 275 nanometers from the thickness-direction phase retardation value of the liquid crystal layer.
