The invention relates to a cinnamate-based photoalignment material with an imide group. The cinnamate-based photoalignment material with the imide group according to the present invention comprises at least one monomer. The monomer comprises: an imide group; a spacer connected to the imide group; a cinnamate-based light reactive group connected to the spacer; and a rodlike group connected to the cinnamate-based light reactive group. According to the invention, unlike the past, the clnnamate-based photoalignment material increases the alignment safety of liquid crystal and remarkably improves heat stability, chemical resistance and mechanical properties by forming a chemical structure in which the imide group, the cinnamate-based light reactive group and the rodlike group are connected linearly. |
