Abstract
A photo alignment material includes a photo alignment polymer and an organic solvent. The photo alignment polymer is prepared by polymerizing a diamine monomer including at least two photo reactive parts represented by the following Chemical Formula 1. In Chemical Formula 1, Rrepresents —(CH)—, —O(CH)— or R, Rand Reach independently represent —H, —O(CH)—CHor and n and m independently represent an integer of from 1 to 8. Thus, change of the orientation of the alignment layer due to the action of an electric stress may be prevented and/or reduced. Therefore, an after—image may be reduced, and display quality is improved.
