Abstract
A display device includes a light guide member, a light source substrate and a liquid crystal panel. The light guide member has a first incidence surface, and an emission surface orthogonal to the first incidence surface. The light source substrate has a light source emitting light toward the first incidence surface, and a substrate on which the light source is arranged. The liquid crystal panel has a second incidence surface arranged to be inclined relative to a surface of the substrate in a position where the liquid crystal panel faces the emission surface of the light guide member. A second angle between the emission surface and the surface of the substrate is greater than 0°, and is equal to or smaller than a first angle between the second incidence surface and the surface of the substrate.
