Abstract
A panel light-emitting structure includes a front panel, a light guide plate, a light-emitting portion, a guide, etc. The light guide plate is formed in a transversely elongated shape having a long side and a short side, and includes an elongated hole extending in a direction of the long side. This forms two light transmission areas. A notch is provided outside the elongated hole at the short side section. This enables an incident light from an LED to the light transmission areas. An outer surface of the light guide plate is formed by an R curved surface. Accordingly, almost all of the light from the LED is totally reflected by the outer surface.
