Disclosed is a liquid crystal display device having an improved display quality. The device includes a substrate; black matrix formed in a matrix pattern on one side of the substrate, wherein the black matrix divides the substrate into a plurality of cell areas; a color filter layer having a red color filter of a first thickness formed in one of the plurality of cell areas, a green color filter of a second thickness which is higher than the first thickness, and a blue color filter of a third thickness which is higher than the second thickness; and a first compensation layer formed by coating the color filter layer and the black matrix with a polymerizable liquid crystal, wherein the first compensation layer is hardened, thereby leveling the substrate, and includes a positive C-plate; and a second compensation layer on another side of the substrate, wherein the second compensation layer is made of one of an A-plate and a biaxial film.
