Abstract:
1. A self-emitting element comprising: a substrate; a light-emitting layer that is disposed between electrodes and that emits light upon applying a voltage between the electrodes, one of the electrodes being deposited on a surface of the substrate; a protective layer that covers an emitting side of the light-emitting layer, forms an interface between the protective layer and an external medium, and has a thickness that allows the light emitted from the light-emitting layer to undergo total reflection at least once at the interface in an area of the light-emitting layer, the protective layer being deposited on another one of the electrodes on an opposite side, as viewed from the light-emitting layer, to the substrate; a reflective layer that is disposed on an opposite side, as viewed from the light-emitting layer, to the protective layer; and an angle changer that is disposed at a periphery of the light-emitting layer, and changes a direction of the light emitted from the light-emitting layer and propagating in the protective layer so that the light is incident on the interface at less than a critical angle.
