  A liquid crystal display capable of reducing the occurrence of defective display due to variations in the initial alignment direction of a liquid crystal alignment control film in a liquid crystal display of an IPS scheme, realizing the stable liquid crystal alignment, providing excellent mass productivity, and having high image quality with a higher contrast ratio. The liquid crystal display has a liquid crystal layer disposed between a pair of substrates, at least one of the substrates being transparent, and an alignment control film formed between the liquid crystal layer and the substrate. At least one of the alignment control films 109 comprises photoreactive polyimide and/or polyamic acid provided with an alignment control ability by irradiation of substantially linearly polarized light.

  An alignment method includes: (1) providing a substrate, applying a coating material formed from any two materials of aromatic dianhydrides, aromatic diamines or diamines containing biphenyl and hexyl in side groups; (2) sputtering a third material which is not coated in step (1) along a direction having an angle not equal to zero with the substrate for conducting a polymerization reaction with the two materials coated in step (1) to generate a reaction product; (3) thermally treating the reaction product. The diamine containing biphenyl and hexyl in side group reacts with the main group to form a side chain, and thus controls the pretilt angle while assisted with physical sputtering to sputter in a certain angle, thereby forming a pretilt direction.
