A photoalignment material includes an alignment polymer, a photoalignment additive including a compound represented by the following Chemical Formula 1 and an organic solvent. In Chemical Formula 1, R1 represents a cyclic compound. A and B independently represent a single bond or —(CnH2n)—. “n” represents an integer in a range of 1 to 12. Each —CH2— of A and/or B may be replaced with R3 represents an alkyl group having 1 to 12 carbon atoms, and each —CH2— of A and/or B may be replaced with —O—. R4 represents In Chemical Formula 1, each hydrogen atom excluding hydrogen atoms of R4 may be replaced with chlorine (Cl) or fluorine (F).Thus, an alignment layer having an orientation may be formed without an alignment polymer having a photoreactive portion, and the density of the alignment layer may be increased.

摘要:
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 lens panel includes a first substrate, a second substrate, and a liquid crystal layer. The first substrate includes a first base substrate, a first electrode disposed on the first base substrate, and a first alignment layer disposed on the first electrode. The first alignment layer includes a unit lens area. The unit lens area includes a first alignment area having a first azimuthal angle and a second alignment area having a second azimuthal angle. The lens panel may be controlled to function as a Fresnel lens by adjusting the azimuthal angle of the alignment layer without electrodes having micro pitch patterns.
