Abstract: A liquid crystal display device includes a pixel electrode having a stem electrode in a first direction and a plurality of branch electrode extending from the stem electrode. An angle between the stem electrode and each of the branch electrode increases as the branch electrodes approach a center of the stem electrode and the angle decreases as the branch electrodes approach an end of the stem electrode.

Abstract: A liquid crystal display (LCD) includes a substrate, an overcoat layer disposed on the substrate, and a pixel electrode disposed on the overcoat layer. The pixel electrode includes a stem electrode and a plurality of branch electrodes. The stem electrode extends in a first direction and in a second direction crossing the first direction to have a cross shape, and the plurality of branch electrodes extends from the stem electrode obliquely to the first direction and the second direction. The overcoat layer includes a base layer and a plurality of ridge patterns which protrude from a surface of the base layer. The plurality of ridge patterns extends in a different direction from the direction in which the plurality of branch electrodes extends.
