Abstract:
This liquid crystal display device comprises electrodes that are formed on at least one of a pair of substrates, and are used for applying voltage onto liquid crystal molecules; a first alignment control layer that is sandwiched between the substrates, and makes the liquid crystal molecules aligned vertically; a liquid crystal layer formed by sandwiching a liquid crystal composition comprising a liquid crystal and a photopolymerizable compound between the substrates, followed by ultraviolet ray irradiation; and a second alignment control layer composed of a UV-cured product formed by the ultraviolet ray irradiation that is formed so that not less than two domains having different threshold voltages are present in a pixel, and at least one of the domains has a threshold voltage higher than the threshold voltage by the first alignment control layer. Liquid crystal display devices having good half-tone viewing angle characteristics are provided.
