    Abstract: A liquid crystal display includes: a first panel including a first electrode; a second panel including a second electrode; and a liquid crystal layer between the first and second panels. The first electrode includes: a central electrode disposed in a central region of a pixel; an outer electrodes extending along a side of the central electrode; and a connection electrode which connects the outer electrode and the central electrode. A slit pattern is defined in the first electrode around the central electrode, and a liquid crystal control pattern is defined in the first electrode in a corner region of the pixel. Horizontal and vertical incisions, which divide the first electrode into a plurality of domains, are defined in the second electrode, an end portion of the outer electrode is disposed to correspond to the corner region, and the end portion of the outer electrode extends farther than the central electrode.
