Abstract
The present invention discloses a multi-domain liquid crystal panel having a wide viewing angle. In the liquid crystal panel including upper and lower substrates and a liquid crystal interposed therebetween, first and second domains are divided via a slit and a pair of side edges, wherein the side edges are bent so that the central region of the pixel electrode is a first distance from a common electrode and the side edges are a second distance from the common electrode. Under an electric field, portions of a liquid crystal in the first and second domains show different orientational alignments.
