Patent ID: 8747967

Claim:
A liquid crystal display, comprising: a first substrate and a second substrate facing each other; an alignment layer disposed on at least one of the first substrate or the second substrate, the alignment layer comprising at least one vertical alignment monomer and a photo-alignment layer separated from and not bound to the at least one vertical alignment monomer; and a liquid crystal layer disposed between the first substrate and the second substrate, wherein the photo-alignment layer comprises a main chain and at least one side chain connected to the main chain, and the at least one side chain comprises at least one vertical photo-alignment material, wherein the at least one vertical alignment monomer and the photo-alignment layer form a single layer, and wherein the at least one vertical alignment monomer is a compound represented by Chemical Formula 26: X-(A) s -(B) t -D [Chemical Formula 26] wherein, in Chemical Formula 26, A is a substituted or unsubstituted C 6 -C 24 aryl group or a substituted or unsubstituted C 3 -C 24 cycloalkyl group, B is a flexible group, D is a first vertical functional group, s is 0 or 1, t is 0 or 1, and X is a thermo-reactive or photo-reactive group, wherein the flexible group B comprises at least one of —O—, —OCO—, —COO—, —OR 1 —, wherein R 1 is H or a C 1 -C 5 alkylene group, —R 2 —, wherein R 2 is a C 1 -C 5 alkylene group, an imide group, and a substituted or unsubstituted alkylene group or alkoxy group having 3 to 20 carbon atoms, wherein the first vertical functional group D comprises at least one of an aryl group in which a C 1 -C 25 alkyl group or an alkoxy group is substituted, a cyclohexyl group in which a C 1 -C 25 alkyl group or an alkoxy group is substituted, a steroid group, a cholesteric group, and —R 3 —(CH 2 ), wherein R 3 is a C 1 -C 5 alkylene group, and wherein the thermo-reactive or photo-reactive group X comprises at least one of a silicon group, an acetylene group, and Chemical Formulae 23 to 25: wherein, in Chemical Formulae 24 and 25, R 1 and R 2 are C 1 -C 5 alkyl groups.
