    Abstract: A photo-alignment composition includes a compound comprising a repeat unit represented by Chemical Formula 1 and a solvent. The photo-alignment composition is coated on a first substrate and a second substrate facing the first substrate, thus forming alignment layers. A liquid crystal layer is formed between the first substrate and the second substrate. The photo-alignment composition includes a compound structure having a high decomposition rate and a functional group capable of a hydrogen bond, which is weaker than a covalent bond. Thus, a hardness of the alignment layer may be improved at a room temperature, and a hydrogen bonding functional group of the photo-alignment composition may be decomposed at a high temperature thus photo-aligning the alignment layer. Therefore, an afterimage of a screen may decrease, and a hardness of the alignment layer may increase.

    Abstract translation: 光取向组合物包括由化学式1表示的重复单元和溶剂构成的化合物。 将光取向组合物涂布在面对第一基板的第一基板和第二基板上，由此形成取向层。 在第一基板和第二基板之间形成液晶层。 光取向组合物包括分解速度高的化合物结构和能够形成氢键的官能团，其弱于共价键。 因此，可以在室温下改善取向膜的硬度，并且光取向组合物的氢键官能团可以在高温下分解，从而对准取向层。 因此，屏幕的残像可能降低，并且取向层的硬度可能增加。

    Abstract: 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).
