Abstract
Disclosed is a optically compensated splay mode liquid crystal display. The device includes: lower and upper substrates opposed with intervening a selected distance and having driving electrodes in their inner surfaces respectively and a liquid crystal layer sandwiched between the lower and the upper substrates and having a plurality of liquid crystal molecules, 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 a middle layer of the liquid crystal layer.
