1. A liquid crystal display device, comprising:
a first substrate comprising a first base substrate and a first alignment layer disposed on the first base substrate; a second substrate comprising a second base substrate facing the first base substrate, and a second alignment layer disposed on the second base substrate; and a liquid crystal layer disposed between the first substrate and the second substrate, the liquid crystal layer comprising a liquid crystal composition, wherein the liquid crystal composition comprises a first liquid crystal compound and a second liquid crystal compound, the first liquid crystal compound comprising at least one compound selected from the group represented by Chemical Formula 1, and the second liquid crystal compound comprising at least one compound selected from the group represented by Chemical Formula 2, wherein each of the first alignment layer and the second alignment layer comprises at least one reactive mesogen selected from the group represented by Chemical Formula 3 and at least one difluoro terphenyl compound selected from the group represented by Chemical Formula 4, or a polymerization product thereof, wherein Chemical Formula 1 comprises: wherein Chemical Formula 2 comprises: wherein Chemical Formula 3 comprises: wherein Chemical Formula 4 comprises: wherein substituents R1 and R2 represent R—, ROCO—, or RCOO—, wherein R comprises an alkyl group having 1 to 15 carbon atoms, the alkyl group comprises an unsaturated or saturated bond, and —CH2— in the alkyl group is substituted or unsubstituted with —O—, —CO—, or —COO—, wherein X and Y independently represent a halogen atom or a hydrogen atom, and do not represent the hydrogen atom at the same time, and wherein R3, R4, and R5 independently represent an alkyl group, an alkenyl group, or an alkoxy group having 2 to 5 carbon atoms. |
