Abstract:
1. A liquid crystal display device comprising: a first substrate including a first alignment layer and a first electrode disposed on one surface thereof; a second substrate opposite to the first substrate and including a second alignment layer and a second electrode disposed on one surface thereof; and an optically compensated bend (OCB) mode liquid crystal layer disposed between the first and second substrates, wherein an alignment layer formed on a unit pixel of the first alignment layer includes at least a pair of rubbed domains having alignment directions perpendicular to each other, the perpendicular alignment directions defined through rubbing, the unit pixel being one of red, green and blue pixels, and the second alignment layer is formed in a same direction as the first alignment layer, and wherein one of the domains has one alignment direction among a first alignment direction corresponding to rubbing the first alignment layer from an upper-left end of the unit pixel toward a lower-right end thereof, a second alignment direction corresponding to rubbing the first alignment layer from a lower-left end of the unit pixel toward an upper-right end thereof, a third alignment direction corresponding to rubbing the first alignment layer from the upper-right end toward the lower-left end, and a fourth alignment direction corresponding to rubbing the first alignment layer from the lower-right end toward the upper-left end, and each of the domains has an alignment direction different from the alignment directions of other ones of the domains.
