Patent ID: 7671949

Claim:
A liquid crystal display comprising: a polarizing plate having a polarizing layer, an optically compensating A-layer and an optically compensating B-layer; and a VA-type liquid cell adjacent to the polarizing plate, wherein the VA-type liquid crystal cell is compensated only by the optically compensating A-layer and the optically compensating B-layer, wherein the optically compensating A-layer comprises a polymer film, wherein the optically compensating B-layer comprises a cholesteric liquid crystal layer, wherein the optically compensating A-layer is on a side of the optically compensating B-layer opposed to the polarizing layer, wherein the optically compensating A-layer meets requirements indicated by the following formulae (I) and (II): 20 (nm)≦Re≦300 (nm) (I) 1.2≦Rth/Re (II) wherein, in the formulae, Re (retardation value in normal direction)=(nx−ny)·d Rth (retardation value in thickness direction)=(nx−nz)·d; where nx, ny and nz respectively denote refractive indices of X axis, Y axis and Z axis in the optically compensating A-layer; the X axis denotes an axial direction presenting a maximum refractive index within the optically compensating A-layer, the Y axis denotes an axial direction perpendicular to the X axis within the optically compensating A-layer, and the Z axis denotes a thickness direction perpendicular to the X axis and the Y axis; ‘d’ denotes the thickness of the optically compensating A-layer, and wherein Re (retardation value in normal direction) of the optically compensating B-layer is about 0.
