An alignment layer and a photo-induced method for setting up the pre-tilt of a liquid crystal molecule in a liquid crystal display are provided to improve the reliability of photo-induced treatment by stabilizing the bulk layer of an organic alignment layer. An alignment layer(22) includes a surface layer having the high photosensitivity and a bulk layer having the photosensitivity lower than the surface layer. The surface layer includes the high sensitivity material capable of photodecomposition. The bulk layer is positioned between the surface layer and substrate. The bulk layer includes the reduction in which the photolysis is doubtful than the high sensitivity material and the surface energy is greater than the high sensitivity material is material. |
