ABSTRACT:
A liquid crystal display device (LCD) is provided, in which a first alignment layer is formed to have at least a pair of domains having alignment directions that are perpendicular to each other on a unit pixel, a second alignment layer is formed in the same direction as the first alignment layer, and an optically compensated bend (OCB) mode liquid crystal layer is disposed between the first and second alignment layers to have at least a pair of domains having alignment directions that are perpendicular to each other, so that horizontal and vertical viewing angles can be improved and phase transition voltage can be lowered.
