Abstract
An alignment film for controlling orientation of liquid crystal molecules is formed of an organic silicon material which includes in its molecule an affinity imparting group for enhancing affinity to the liquid crystal molecules and an orientation characteristic imparting group for controlling orientation of the liquid crystal molecules. The affinity imparting group is at least one selected from the group comprising a vinyl group, an alkylene group, and a cyanoalkyl group, and the orientation characteristic group is at least one selected from the group comprising a phenyl group, a substituted phenyl group, a phenyl-alkyl group, a substituted phenyl-alkyl group, a branched alkyl group having carbon atoms of 3 to 12. Preferably, the organic silicon material includes organopolysilsesquioxane having a cage structure or a partially cleaved cage structure. A liquid crystal panel having the alignment film, and electronic equipment provided with the liquid crystal panel are also provided.
