Abstract: An object of the present invention is to provide a photoalignment layer with a more reliable absorption anisotropy parameter as a photoalignment layer that allows for reduced AC image-sticking. Specifically, provided is a photoalignment layer, obtained by exposure to polarized UV radiation, that has a maximum ΔA (=A1−A2, where A1 is the absorbance in a direction parallel to a vibration direction of the polarized UV radiation, and A2 is the absorbance in a direction parallel to the vibration direction of the polarized UV radiation) of 0.35 or more per micrometer of layer thickness in a range of 230 to 380 nm.

Abstract: There is provided a polymerizable composition, by which discoloration or alignment defects are less likely to occur when a filmy polymer, which is obtained by adding a polymerizable compound to the polymerizable composition and polymerizing this composition, is irradiated with ultraviolet light. There are also provided a polymer obtained by polymerizing the polymerizable composition, and an optically anisotropic body using the polymer. The present invention provides a polymerizable low-wavelength dispersive or polymerizable reverse-wavelength dispersive compound having a partial structure represented by Formula (Z-0). Further, the present invention provides a composition containing the compound; a polymer obtained by polymerizing the composition; and an optically anisotropic body obtained by using the polymer.
