    Abstract: The present invention provides a polymer stabilization alignment liquid crystal display panel having a plurality of pixel regions defined by plurals of data lines and gate lines. Each pixel region includes a main region and a sub region, and a first pixel electrode and a second pixel electrode correspond to the main region and the sub region respectively, wherein each of the data lines has a first width adjacent to the main display region and a second width adjacent to the sub display region, and the second width is larger than the first width. Each first pixel electrode is separated from the adjacent data line and thereby forming a gap therebetween. Each second pixel electrode partially overlaps the adjacent data line to form an overlap width. Accordingly, the present invention not only can increase the aperture ratio, but also well control the liquid crystal molecules located near the data lines.
