Abstract:
1. A liquid crystal display device, comprising: a first substrate; a second substrate; a liquid crystal layer which is sandwiched between the first and the second substrates; pixel portions which are arranged on the first substrate in a matrix array; a pixel electrode which is formed in the pixel portion and applies an electric field to the liquid crystal layer; a first organic alignment film formed on a liquid-crystal-layer side of the first substrate and having a liquid-crystal-layer side surface and a pixel electrode side surface; and a second organic alignment film formed on a liquid-crystal-layer side of the second substrate and having a liquid-crystal-layer side surface, wherein a first slow axis formed in the liquid-crystal-layer side surface of the first organic alignment film by aligning polymer chains due to the radiation of light and a second slow axis formed in the liquid-crystal-layer side surface of the second organic alignment film by aligning polymer chains due to the radiation of light are arranged to cross each other, the first organic alignment film is an index ellipsoid having retardation, the second organic alignment film is an index ellipsoid having retardation, a direction along which liquid crystal molecules tilt when an electric field is applied to the liquid crystal layer, is different from one of the first slow axis and the second slow axis, and a main chains in molecules of the first organic alignment film are arranged to form the first slow axis.
