The invention provides a display device with enhanced display quality. The display device includes a lower polarizing plate, an array substrate, an opposite substrate, a liquid crystal layer and an upper polarizing plate. The array substrate includes a pixel electrode and a lower alignment layer. The pixel electrode has a planar-type electrode portion and a plurality of branch electrode portions extended from the planar-type electrode portion in a first direction, which is formed at about 45 degrees with respect to a first polarization axis. The lower alignment layer is formed on the pixel electrode to be aligned in the first direction. The opposite substrate includes a planar-type common electrode facing the pixel electrode and an upper alignment layer. The upper alignment layer is formed on the common electrode to be aligned in an opposite direction of the first direction.
