Abstract
A display device includes: a light source; a display panel capable of receiving the light from a first surface side and transmitting the light to a second surface side; and a light guiding member. The display panel is inclined with respect to an orthogonal plane orthogonal to an optical axis of the light. The light guiding member has an output surface framed by an output port of the light and inclined with respect to the orthogonal plane. An inclination direction of the display panel is identical to an inclination direction of the output surface. The light guiding member has such a shape that a distance between inner surfaces of the light guiding member and the optical axis increases toward the first surface side from the light source side, and the inner surfaces opposing each other at positions orthogonal to the optical axis are not uniform in curvature.
