Abstract: According to an aspect, a display device includes: a display panel configured to transmit light; and an illumination device provided on a rear surface side of the display panel. The illumination device includes a plurality of light sources configured to emit light, and a light guiding member that has translucency and is arranged between the light sources on the rear surface side of the display panel. The light guiding member has a plurality of holes each of which opens in a first direction intersecting with a rear surface of the display panel and in each of which a corresponding one of the light sources is disposed, and a light guiding portion surrounding the holes. A rear surface of the light guiding portion is provided with a first inclined surface inclined with respect to the first direction and a plane orthogonal to the first direction.
