Abstract: According to an aspect, a display device includes: a substrate; a plurality of pixels; a first anisotropic diffusion layer and a second anisotropic diffusion layer that are layered; and a plurality of light emitting elements interposed between the first anisotropic diffusion layer and the substrate. The first anisotropic diffusion layer and the second anisotropic diffusion layer each include a high refractive index region and a low refractive index region in a mixed manner. An absolute value of a first angle formed by a boundary between the high refractive index region and the low refractive index region of the first anisotropic diffusion layer and a direction perpendicular to the substrate is different from an absolute value of a second angle formed by a boundary between the high refractive index region and the low refractive index region of the second anisotropic diffusion layer and the direction perpendicular to the substrate.
