ABSTRACT:
A liquid crystal display with multi cell gaps includes first and second panels facing each other, and a pixel electrode, a common electrode and a storage electrode formed at one of the first and the second panels. A liquid crystal capacity is formed between the pixel electrode and the common electrode where a liquid crystal material is interposed, and a storage capacity being formed between the pixel electrode and the storage electrode where an insulating layer is interposed. The storage capacity is differentiated depending upon the cell gaps. The gray voltages applied to the pixel electrode have positive and negative gray voltages. The reference value of the positive and the negative gray voltages is varied depending upon the grays. With this structure, flicker correction is uniformly made even in a liquid crystal display where the kick-back voltage is varied per the respective grays.
