Abstract
A liquid crystal display includes a first substrate and a second substrate facing each other; a switching element disposed on the first substrate; a pixel electrode connected to the switching element and supplied with a data voltage; an opposing electrode disposed on the second substrate; and a liquid crystal layer disposed between the first substrate and the second substrate and including liquid crystal molecules. The pixel electrode includes a cutout and a liquid crystal direction controller that are alternately disposed. The cutout and the liquid crystal direction controller divide the pixel electrode into a plurality of sub-regions, and inclination directions of the liquid crystal molecules are different according to the plurality of sub-regions when the pixel electrode is supplied with the data voltage. The liquid crystal direction controller is concave downward or convex upward with respect to a surface of the first substrate.
