摘要:
An organic EL device includes an organic EL panel, an ellipsoidal reflector, a phosphor, and a laser. The organic EL panel includes a substrate and at least one organic EL element, and the substrate includes at least one light incident portion on which light is incident from the outside. The ellipsoidal reflector is disposed outside the organic EL panel in such a manner that the phosphor is disposed at a first focal point of the reflector and the light incident portion of the substrate is positioned at a second focal point of the reflector. The laser is disposed outside the organic EL panel in such a manner that the phosphor can be irradiated with a laser beam. Light emitted from the phosphor enters the substrate from the light incident portion. The light emitted from the phosphor that has entered the substrate diffuses in the in-plane direction of the substrate.
