Patent ID: 7859631

Claim:
A multi-domain liquid crystal display device, comprising: first and second substrates; a liquid crystal layer between the first and second substrates; first and second data lines for applying a data signal on the first substrate; first and second gate lines for applying a gate signal, the gate lines crossing the first and second data lines to define a pixel region, wherein the pixel region has a multi-domain structure which includes a slit; a thin film transistor (TFT) near each crossing of the first gate line and the first data line; a common electrode on the second substrate; a pixel electrode connected to a drain electrode of the thin film transistor in the pixel region; and an auxiliary electrode line electrically connected to the first gate line or the second gate line, the auxiliary electrode line and the multi-domain structure distorting an electric field applied between the common electrode and the pixel electrode to thereby form at least two domains in the pixel region during an operation of the multi-domain liquid crystal display, wherein the auxiliary electrode line is formed between the pixel electrode and the first data line or between the pixel electrode and the second data line and the auxiliary electrode line is spaced apart from the first and second data lines, wherein the common electrode includes the slit, and wherein the auxiliary electrode line takes advantage of the gate signal applied to the first and second gate lines to form the multi-domain, wherein the gate line has a larger width than the auxiliary electrode line, wherein the auxiliary electrode line comprises a first auxiliary electrode line extending from the first gate lines to the pixel region in a direction parallel to the first data line and a second auxiliary electrode line extending from the second gate line to the pixel region in a direction parallel to the second data line, wherein the auxiliary electrode line does not overlap with the pixel electrode.
