Abstract
The present invention provides a liquid crystal display having improved screen quality by preventing abnormal light leakage due to ions in a pixel. The present invention comprises: an array substrate whereon a plurality of gate lines and data lines are arranged to be perpendicular to each other, a TFT is formed at the intersection of the lines and a pixel electrode is formed in a pixel region defined by the lines; a color filter substrate combined with the array substrate, whereon a color filter is formed corresponding to the pixel region, a block matrix is formed corresponding to the interface of pixels and a counter electrode is formed on the whole surface including the color filter and the black matrix; and a liquid crystal layer comprising a plurality of liquid crystal molecules interposed between the array substrate and the color filter substrate, wherein the pixel electrode has a rectangular shape and a plurality of acute angle Tips are formed on the edges thereof.
