Since the LEDs are arranged in an L-shape and the light emitting diodes for side irradiation are arranged on the surface of the side LED board on the front LED board side, the light irradiation to the sides by the light emitting diodes for side irradiation is surely performed. In addition, when viewed from the side where irradiation by the side-emitting LED is performed, the front-emitting LED is not blocked by the side LED substrate.
