A display device includes a display panel, a plurality of light sources arranged in a first direction orthogonal to a normal direction of the display panel, a light guide panel on which light from a plurality of light sources is incident and including an emission surface that emits light toward the display panel, and a first optical member disposed between the display panel and the light guide panel and including a first surface opposing the emission surface of the light guide panel, a second surface provided opposite to the first surface to oppose the display panel, a Fresnel lens provided on the first surface, and an optical array provided on the second surface. As viewed in at least one of the first direction and a second direction orthogonal to both the normal direction and the first direction, the Fresnel lens emits light passing through a center of the display panel.
