Patent ID: 7649600

Claim:
A liquid crystal display device comprising: a lower substrate; a plurality of pixel electrodes on the lower substrate; a lower alignment layer on the pixel electrodes and having a predetermined alignment direction; an upper substrate spaced apart from the lower substrate and having an opposite surface facing the lower substrate; an opposite electrode on the opposite surface; an upper alignment layer on the opposite electrode and having the predetermined alignment direction of the lower alignment layer; an upper protrusion between the upper substrate and the opposite electrode and extending in a direction crossing the predetermined alignment direction; and an optically compensated bend (OCB) mode liquid crystal layer between the lower alignment layer and the upper alignment layer, wherein the lower substrate has opening areas and non-opening area surrounding the opening areas, wherein each of the pixel electrodes is on a corresponding one of the opening areas, and the upper protrusion is between adjacent pixel electrodes and on a region corresponding to the non-opening area between the adjacent pixel electrodes.
