Light-emitting device including a dual emission panel

摘要

There is a problem in a dual emission device emitting light out of both surfaces that an image on the surface and an image on the rear surface are different from each other (either image is mirror-reversed). A dual emission device is disclosed in which either light emitted from the light-emitting device is reflected by glass including a semi-transmissive film to display on glass an image same as another image obtained also from the light-emitting device, and simultaneously, external information can be viewed through the glass. A mirror can be arranged between the dual emission device and the glass including a semitransparent film.

主权项

1. A semiconductor device comprising:
a light-emitting device comprising:
a substrate having a flat surface; anda light emitting layer over the substrate; and an optical device adjacent to the light-emitting device, wherein the optical device includes a first surface and a second surface, wherein the first surface is flat and parallel to the flat surface, wherein the second surface is a concave surface, wherein the optical device is configured to allow light from the light-emitting device to be extracted from the second surface, and wherein the optical device is capable of adjusting an optical path at the second surface.
