Abstract: A novel display device that is highly convenient, useful, or reliable is provided. The display device includes a light guide plate, a display panel, and an intermediate layer, and the light guide plate includes a first surface and a second surface. The first surface is irradiated with light, the second surface has a function of distributing light, the second surface is in contact with the intermediate layer, and the second surface has a first refractive index N1 in a region in contact with the intermediate layer. The display panel faces the second surface, the display panel is in contact with the intermediate layer, and the display panel has a function of scattering the distributed light. The intermediate layer includes a region positioned between the second surface and the display panel, and the intermediate layer has a second refractive index N2 in a region in contact with the second surface. The second refractive index N2 is smaller than the first refractive index N1.
