<p><P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device, reducing the occurrence of display failure due to fluctuation in the initial alignment direction of a liquid crystal alignment control film in an IPS system liquid crystal display device, achieving stable liquid crystal alignment, having excellent mass productivity, and improved in contrast ratio to have high grade image quality. <P>SOLUTION: The liquid crystal display device includes: a pair of substrates 101, 102, at least one of which is transparent; a liquid crystal layer 110' disposed between the paired substrates; an electrode group formed on at least one of the paired substrates for applying an electric field to the liquid crystal layer; a plurality of active elements 115 connected to the electrode group; and an alignment control film 109 disposed on at least one of the paired substrates, wherein at least the one alignment control film is an alignment control film made of photo-reactive polyimide and polyamide and polyamide acid ester to which alignment regulating force is applied by irradiating substantially linearly polarized light. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
