The utility model provides a flat light source device. The flat light source device comprises a light guide plate, at least one light bar, a reflector and a diffuser, wherein the light guide plate is provided with an upper first surface and a lower second surface; the at least one light bar is provided with a plurality of LEDs (light emitting diode) and arranged on one side of the light guide plate, and the LEDs are arranged inside the light guide plate and emit light; the reflector is arranged outside the second surface and used for reflecting light; the diffuser is arranged outside the first surface and used for diffusing reflected light. Due to the fact that the LEDs are preset inside dies during manufacturing of the light guide plate, the LEDs and the light guide plate are integrally formed, further light source losses can be avoided, and the efficiency of the flat light source device can be improved. |
