ABSTRACT:
A liquid crystal display device adopting a storage-on-common method is disclosed to prevent the operation of a unit pixel with a point deficiency, such as a brilliant spot, at its occurrence, thereby preventing degradation of a picture quality caused due to the defective pixel. Because the defective pixel is controlled to turn black by the use of a repair pattern, the picture quality degradation due to the defective pixel is prevented when the liquid crystal display device is driven.
