摘要： Provided is a light emitting device of an electronic device, provided with a DLP (Digital Light Processing) projector and a display unit, which is configured in such a manner that the light generated by the operation of the DLP projector can be re-used as a backlight light of the display unit. The disclosed light emitting device includes a first mirror for projecting a light of the DLP projector on a flat area provided ahead of the first mirror in an intermediate operation state of the first mirror; a light concentration mirror for converging the light projected on the flat area, the light concentration mirror being provided at a position adjacent to the flat area; and an optical fiber for transferring the light converged by the light concentration mirror to the display unit and enabling re-use of the transferred light as a light for a backlight of the display unit.
