Homeotropic alignment liquid crystal display having multi-domain
The present invention provide a homeotropic alignment liquid crystal display having a multi-domain which is capable of obtaining symmetrical viewing angles and simultaneously preventing color shift.An upper substrate and a lower substrate are opposed each other to be spaced apart and a liquid crystal layer interposed between inner surfaces of the upper and lower substrates. A first electrode and a second electrode are formed on the inner surface of the lower substrate, wherein the first electrode and the second electrode form an electric field for driving liquid crystal molecules. Further, homeotropic alignment layers are interposed between the lower substrate and the liquid crystal layer and between the upper substrate and the liquid crystal layer respectively. After a selected voltage is applied to the first and second electrodes, there are formed simultaneously a first electric field having a selected angle with a first direction and a second electric field making a symmetry with the first electric field with respect to the first electric field and the first direction. Therefore, the liquid crystal molecules are tilted in their left side and right side with respect to the center lines of electric fields thereby forming four symmetric liquid crystal domains within one pixel region.
