Abstract: A display panel includes a liquid crystal cell, a light guide plate, and at least one light source. The light guide plate is attached to a surface of the liquid crystal cell in a thickness direction of the liquid crystal. The light guide plate includes a first surface, a second surface and side surfaces. In a thickness direction of the light guide plate, the first surface is opposite to the second surface, and the side faces are located between the first surface and the second surface. The first surface is closer to the liquid crystal cell than the second surface. A light source is disposed on at least a partial region in at least one side face. The light guide plate is configured such that light incident on the second surface in light from the light source is totally reflected, and then exits from the first surface.
