Abstract:
A liquid crystal display device having a plurality of pixels formed by a pair of substrates facing each other with a space in which substantially uniform liquid crystal domains are formed, each of said pixel including red, green and blue sub-pixels, comprising: a first polymer network formed within said space below the area of said red sub-pixels;a second polymer network formed within said space below the area of said green sub-pixels; anda third polymer network formed within said space below the area of said blue sub-pixels;wherein said first, second and third polymer networks, being formed by adding a small amount of monomers in said uniform liquid crystal domains with a concentration ratio in weight ranging from 0.1% to 5%, comprise different structures and modify the electro-optical characteristic of said uniform liquid crystal domains to minimize the difference in phase retardation introduced by said uniform liquid crystal domains with respect to red, green and blue light for reducing the color dispersion of said liquid crystal display device.
