Abstract:
1. A multi-domain liquid crystal display device comprising: a first substrate; a second substrate; a plurality of gate lines provided in one direction on the first substrate; a plurality of data lines provided substantially perpendicular to the plurality of gate lines to define a plurality of pixel regions including a first area and a second area; a common electrode and a pixel electrode which generate an electric field parallel to the first and second substrates within the first area to improve luminance; a common electrode and a pixel electrode which generate an electric field within the second area to decrease color shift; an alignment layer over the first substrate, the alignment layer being rubbed; and a liquid crystal layer formed between the first substrate and the second substrate, wherein the rubbing direction of the alignment layer is substantially parallel to the gate line in the first area and the second area of the pixel region, the common electrode in the first area includes a first common electrode and a second common electrode disposed respectively in the angle of about 5 degrees to about 20 degrees with respect to the rubbing direction and the pixel electrode in the first area includes a first pixel electrode and a second pixel electrode disposed respectively in the angle of about 5 degrees to about 20 degrees with respect to the rubbing direction so that the first common electrode and the first pixel electrode are respectively symmetric to the second common electrode and the second pixel electrode with respect to the rubbing direction, wherein the common electrode in the second area includes a third common electrode and a fourth common electrode disposed respectively in the angle of about 45 degrees with respect to the rubbing direction and the pixel electrode in the second area includes a third pixel electrode and a fourth pixel electrode disposed respectively in the angle of about 45 degree with respect to the rubbing direction so that the third common electrode and the third pixel electrode are respectively symmetric to the fourth common electrode and the fourth pixel electrode with respect to the rubbing direction.
