Abstract:
A liquid crystal display device superior in mass productivity and improved image quality with a higher contrast ratio by decreasing the occurrence of defective display due to the disorder of the initial liquid crystal alignment and realizing stable alignment of liquid crystals, comprising: a pair of substrates 101 and 102, at least one of which is transparent; a liquid crystal layer 110′ disposed between the pair of substrates; a group of electrodes formed on at least one of the pair of substrates to apply an electric field to the liquid crystal layer; plural active elements 115 connected to the group of electrodes; and an orientation control film 109 disposed on at least one of the pair of substrates, wherein said orientation control film made of a photosensitive polyimide, a polyamide acid ester and a polyamide acid is given orientation control ability by being irradiated with substantially linearly polarized light.
