Claim Text:
1. A liquid crystal display, comprising: a first substrate and a second substrate facing each other, a first alignment layer disposed on the first substrate, the first alignment layer consisting of a vertical photo-alignment material; a second alignment layer disposed on the second substrate, the second alignment layer consisting of a vertical alignment material; and a liquid crystal layer disposed between the first alignment layer and the second alignment layer, wherein: the vertical photo-alignment material comprises a first vertical functional group and a photo-reactive functional group, the vertical alignment material comprises a second vertical functional group and does not comprise the photo-reactive functional group, wherein the first alignment layer comprises a different material from the second alignment layer, wherein the first alignment layer is an irradiated layer and the second alignment layer is a non-irradiated layer, wherein the first alignment layer is pretilted, and the second alignment layer is not pretilted, wherein the vertical photo-alignment material comprises a polymer formed from a diamine represented by the following Formula 21, a vertical diamine including a cholesteric group, and an acid anhydride represented by the following Formula 11, and wherein the vertical alignment material comprises a polymerization product of a diamine represented by the following Formula 22 or Formula 23 and an acid anhydride of Formula 11, and does not comprise the photo-reactive functional group.
