ABSTRACT:
The LCD device of the present invention provides multi domains without an additional rubbing process to align the liquid crystals in different alignment directions. The LCD device includes a common electrode having slit patterns so as to form a fringe field between the common electrode and the pixel electrode. Auxiliary electrodes are formed on the organic passivation layer to intensify the fringe field and overlap the data lines. The pixel electrode overlaps the auxiliary electrodes. Additionally, the black matrix pattern is formed in the position corresponding to the slit pattern. An additional inorganic layer is formed between the organic passivation layer and the thin film transistors.
