Abstract: A composition for aligning includes a macromolecular compound and a reactive mesogen. The macromolecular compound is formed by a condensation polymerization reaction of a dianhydride monomer, and a diamine monomer including a photo reactive group. Thus, the composition for aligning includes the reactive mesogen, so that the reactive mesogen is not included in a liquid crystal layer.
