1. A liquid crystal display comprising:
a first substrate; a second substrate facing the first substrate; a liquid crystal layer having a negative dielectric anisotropy and disposed between the first substrate and the second substrate; a thin film transistor disposed on the first substrate; a first electrode connected to the thin film transistor; a second electrode overlapping the first electrode; an insulating layer disposed between the first and second electrodes; and a first alignment layer disposed on the first electrode and comprising a photo-alignment layer, wherein the photo-alignment layer is formed by polymerizing a diamine and at least one of a cyclobutane dianhydride (CBDA) represented by Formula (A) and a cyclobutane dianhydride (CBDA) derivative represented by Formula (B): wherein, in Formula (B), X1, X2, X3, and X4 are independently hydrogen, fluorine, or an organic compound, and at least one of X1, X2, X3, and X4 is not hydrogen, and wherein the first alignment layer comprises at least one repeating unit represented by Formula (C), Formula (D), and a Formula (E): wherein, in Formula (C), Formula (D), and Formula (E), X5, X6, X7, and X8 are compounds coupled to two amino groups (—NH2) of adjacent diamines, A, B, C, D, E, and F are unit 1 or unit 2, andwherein in Formula (D) and Formula (E), X1, X2, X3, and X4 are independently hydrogen, fluorine, or an organic compound, and at least one of X1, X2, X3, and X4 is not hydrogen. |
