Abstract:
1. A multi-domain LCD device comprising: first and second substrates; a plurality of gate and data lines crossing one another on the first substrate, for defining a plurality of pixel regions; a pixel electrode formed within a pixel region of the plurality of pixel regions, the pixel electrode having an electric field induction window that divides the pixel region into a plurality of domains; auxiliary electrodes, which are formed on a same layer as the gate line, including a first auxiliary electrode overlapping with an edge of the pixel electrode to completely surround the pixel electrode and a second auxiliary electrode overlapping the electric field induction window; a black matrix film formed only in regions of the gate line, the data line and a TFT on the second substrate; a color filter film on the black matrix film; a common electrode on the color filter film; a circle type dielectric structure on the common electrode in the plurality of domains; and a liquid crystal layer between the first and second substrates, wherein the auxiliary electrodes are formed in at least two of close loop type within pixel region and formed on a different layer from the pixel electrode, and wherein the first auxiliary electrode and the second auxiliary electrode are formed as one body and electrically connected with the common electrode, wherein the second auxiliary electrodes between the plurality of domains are formed along the electric field induction window and formed as a cross pattern.
