Abstract
A liquid crystal display includes a pixel electrode including a first subpixel electrode and a second subpixel electrode spaced apart with a gap therebetween, a common electrode facing the pixel electrode, and a liquid crystal layer formed between the pixel electrode and the common electrode and including a plurality of liquid crystal molecules. The first and second subpixel electrodes include a plurality of branches, and each of the first and second subpixel electrodes includes a plurality of subregions. The branches extend in different directions in different subregions.
