Abstract

A liquid crystal display apparatus includes a polarization plate, a twisted-mode type liquid crystal layer having coexistent regions with different twisted directions of liquid crystal orientations and different tilt angles of liquid crystal molecules within one pixel, and a compensation layer, having biaxial refractive anisotropy, interposed between the polarization plate and the liquid crystal layer.
