Abstract:
An object of the present invention is to provide a liquid crystal display device that has an excellent mass-productivity and gives an image improved by the reduction of the chromaticity difference between white display and black display, the reduction of coloring and luminance in black display, and the improvement of the contrast ratio. In the present invention, of a pair of alignment films 131 and 132 formed on a pair of substrates 101 and 102, respectively, the alignment film 132 formed on the glass substrate 102 on the observer side is made of a material obtained by adding a photoisomerized compound to a photosensitive polymer and has anisotropic absorption all over the visible light wavelength region (approximately 400 nm to 750 nm).
