Abstract
An organic EL display device capable of suppressing a change in tint in a case where white display is visually recognized from an oblique direction. The organic EL display device includes an organic EL display element and a light absorption anisotropic layer, in which the light absorption anisotropic layer is a light absorption anisotropic layer formed of a composition containing a liquid crystal compound and a dichroic substance, an angle between a transmittance central axis of the light absorption anisotropic layer and a normal line of a layer plane of the light absorption anisotropic layer is 0° or more and 450 or less, and A(λ) of the light absorption anisotropic layer represented by Expression (1) A(λ)={kz(λ)−(kx(λ)+ky(λ))/2}×d, is 15 to 225 nm at a maximal absorption wavelength of the light absorption anisotropic layer.
