Abstract

Provided is a laminate exhibiting excellent reverse wavelength dispersibility, a circularly polarizing plate, and a display device. The laminate includes a first optically anisotropic film and a second optically anisotropic film, in which both of the first optically anisotropic film and the second optically anisotropic film have a slow axis in an in-plane direction, a maximum absorbance X in a wavelength range of 700 to 900 nm in a slow axis direction and a maximum absorbance Y in a wavelength range of 700 to 900 nm in a fast axis direction of the first optically anisotropic film are different from each other, and the slow axis of the first optically anisotropic film and the slow axis of the second optically anisotropic film are parallel with or perpendicular to each other.
