Abstract
Provided is an optically anisotropic film exhibiting excellent reverse wavelength dispersibility, a laminate, a circularly polarizing plate, and a display device. The optically anisotropic film includes a J-aggregate having an absorption peak of a J-band on a wavelength side longer than a wavelength of 700 nm, in which an absorption at a wavelength of 700 to 900 nm in a fast axis direction of the optically anisotropic film is larger than an absorption at a wavelength of 700 to 900 nm in a slow axis direction of the optically anisotropic film.
