摘要:
The present invention provides photo-reactive compound. The photo-reactive compound, in which chains are combined to a polymer backbone that is used for a photo-alignment layer compound, is represented by the following Formula 1 or Formula 2. L denotes a substituted or unsubstituted alkyl group having at least 1 but no more than 18 carbons, V denotes a substituted or unsubstituted alkyl group having at least 1 but no more than 18 carbons, R1, R2, and R3 each denote H or a substituted or unsubstituted alkyl group having at least 1 but no more than 18 carbons, X+Y=1, 0

A display panel includes a lower substrate, an upper substrate and a liquid crystal layer. The liquid crystal layer includes a plurality of domains, a horizontal domain boundary texture area and a vertical domain boundary texture area. The domains are disposed in a matrix shape. The horizontal domain boundary texture area extends in a first direction in a boundary between the domains adjacent to each other in a second direction and has a slope of a liquid crystal slowly (e.g., less) inclined compared to that of the domains. The vertical domain boundary texture area extends in the second direction in a boundary between the domains adjacent to each other in the first direction and has a width larger than that of the horizontal domain boundary texture area.

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, R1 represents —(CH2)n—, —O(CH2)n— or R2, R3 and R4 each independently represent —H, —O(CH2)m-1—CH3 or 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.

A photoalignment method includes irradiating light in a first direction to a first alignment layer, and irradiating light in a second direction opposite the first direction, after disposing a first mask on the first alignment layer.
摘要:
An alignment substrate includes a substrate and an alignment layer. The substrate includes a plurality of unit pixel areas. Each of the unit pixel areas includes a plurality of sub-pixel areas arranged in a matrix configuration. The alignment layer is on the substrate and has polymer chains protruding from a surface of the alignment layer. The alignment layer has a plurality of alignment vectors in which the polymer chains are pretilted according to the sub-pixel areas. The alignment vectors corresponding to adjacent sub-pixel areas point in different directions from each other.
