Recently, active matrix liquid crystal (LC) displays have been intensively investigated for realizing full color television sets. In order to obtain a high quality picture LC-TV, the color filter is important. Various processes for manufacturing color filters have been studied, such as dispersion, dyeing, printing, electrodeposition, color vacuum evaporation, multilayer interference film, sublimation transfer, photographic coloration, electrophotography, tinted polymer polymerization, and complex processes (combinations of two or more processes). Of these processes, the dispersion, dyeing, and printing processes, which are considered particularly promising, shall be discussed below.
