Abstract

A display device includes a display component, a light source, a light guide plate, a spacer member, and a biasing member. The display component displays images. The light source emits light. The light guide plate guides the light emitted from the light source to the display component. The light guide plate has a light incident face on which the light emitted from the light source is directly incident. The spacer member is disposed in a region other than where the light guide plate and the light source are opposite each other such that the spacer member maintains a specific spacing between the light source and the light incident face of the light guide plate. The biasing member is arranged to bias one of the light source and the light guide plate towards the other of the light source and the light guide plate.
