Abstract
An object of the present invention is to provide a laminate in which the coloring of reflected light is reduced. The laminate includes an optical film having a light absorption anisotropic film formed using a composition including a dichroic substance and having a transmittance of more than 50%, a λ/4 plate, and a metal electrode in this order, in which in a case where a degree (%) of polarization at a wavelength of λ of the optical film is defined as P(λ) and a reflectance (%) at the wavelength of λ of the metal electrode is defined as R(λ), a ratio of a minimum value of R/P to a maximum value of R/P at wavelengths of 450 nm, 550 nm, and 650 nm is more than 85%.
