An alignment layer (3A,4A,3B,4B) for setting the orientation of liquid crystal molecules (2) consists of an organic silicon-based material (typically containing a polysiloxane), whose molecules include a chemical group which enhances the affinity of the alignment layer material for the liquid crystal materials (i.e. favours molecular attraction) and a further chemical group which enhances the orientation of the liquid crystal molecules with respect to the alignment layer. The affinity enhancing group may contain at least one of the following chemical groups: a vinyl group, an alkylene group and a cyanoalkyl group. The chemical group which enhances the orientation of the liquid crystal molecules consists of at least one of the following: a phenyl group, a substituted phenyl group, a phenyl-alkyl group, a substituted phenyl-alkyl group, and a branched alkyl group containing 3 to 12 carbon atoms. Preferably, the organic silicon-based material includes organopolysilsesquioxane exhibiting either a cage structure or a partially cleaved cage structure. A method of fabricating the alignment layer is also described. Furthermore, the application of the alignment layer (3A,4A,3B,4B) to liquid crystal display panels (1A,1B) in various electronic equipment (1100,1200,1300,300) is discussed. |
