Abstract:
An optically compensated splay (OCS) mode liquid crystal display (LCD) comprising:lower and upper substrates opposed with intervening a selected distance and having driving electrodes in their inner surfaces, respectively; a liquid crystal layer sandwiched between the lower and the upper substrates and having a plurality of liquid crystal molecules; and a phase compensation plate at an outer surface of the upper substrate or the lower substrate, the phase compensation plate having liquid crystal molecules arranged such that long axes thereof are perpendicular to those of the liquid crystal molecules of a middle layer of the liquid crystal layer, wherein no voltage is applied to the driving electrodes, the liquid crystal molecules are arranged in a bend state, and wherein a voltage above a critical voltage is applied to the driving electrodes, the liquid crystal molecules are arranged in a splay state which makes a symmetry of up and down with respect to the middle layer of the liquid crystal layer.
