A lighting device includes a light guide plate, a first light source, a second light source, and a case. The light guide plate includes plate surfaces and an outer peripheral surface. One of the plate surfaces is configured as a light exiting surface. Sections of the outer peripheral surface on opposite sides from each other relative to the center of the light exiting surface are configured as a first light entering surface and a second light entering surface, respectively. The first light source is disposed opposite the first light entering surface. The second light source is disposed opposite the second light entering surface. The case includes an annular wall portion surrounding an outer circumference of the light guide plate, the first light source, and the second light source. The annular wall portion includes light source non-disposing areas between the first light entering surface and the second light entering surface.
