Abstract

Liquid crystal display (LCD) has sub-pixel domains in each of pixels to obtain a wide viewing angle. The sub-pixel domains are formed by divided orientation alignment in which the sub-pixel domain are subjected to rubbing in different directions opposite to each other. The liquid crystal has a splay-type TN deformation structure in the first sub-pixel domain and a normal TN deformation structure in the second sub-pixel domain. The pre-tilt angles of the liquid crystal in the first domain and second domain are selected to obtain a wide viewing angle. The LCD has a shield pattern for for shielding disclination causing afterimages and storage capacitor electrodes having a function as a signal lines.
