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 and including an even number of rubbed domains in one unit pixel, the even number of the rubbed domains in the one unit pixel being at least two, wherein liquid crystal molecules in two adjacent ones of the rubbed domains are arranged in directions perpendicular to each other, the directions of the rubbed domains that are perpendicular to each other being defined through rubbing, 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 wherein corresponding domains respectively formed on the first alignment layer and the second alignment layer are rubbed in a same direction.
