摘要 <p>The phase difference plate for a circularly polarizing plate includes a first optically anisotropic layer; and a second optically anisotropic layer, in which the first and second optically anisotropic layers contain a liquid crystal compound that is helically aligned around a helical axis which is in a thickness direction of each of the layers, the liquid crystal compound has a same helix direction in the first optically anisotropic layer and in the second optically anisotropic layer, and a helix angle of the liquid crystal compound each in the first optically anisotropic layer and in the second optically anisotropic layer is in a predetermined range. The phase difference plate can sufficiently suppress the mixing of black with another color observed in the front direction when being stuck as a circularly polarizing plate on a display apparatus.</p>
