1. A display element, comprising:
- an emission layer having a light-emitting layer that emits light by a voltage applied between electrodes;
a transmission layer that transmits the light emitted from the light-emitting layer; and
a total reflection surface in the transmission layer, that is capable of totally reflecting at least a part of the light radiated from the light-emitting layer in a direction of emission of the light-emitting layer.

Abstract
The invention provides a display panel having high light-extraction efficiency which can be easily produced. The present invention provides a display panel including an emission layer having a light-emitting layer and a transparent member (transmission layer) having recesses, an inclined surface of the recesses acting as a total reflection surface to reflect part of light radiated from the light-emitting layer. The display panel changes the optical path by total reflection, thus having no light-absorption loss and having high light-extraction efficiency. Since there is no need to deposit a reflecting film, it is easy to produce. Thus, a high-intensity display panel can be provided at low cost.

16. A method for producing a display panel, comprising:
-
forming an emission layer on a surface of a substrate, the emission layer including a plurality of light-emitting layers that generate light by a voltage applied between electrodes;
forming a transparent panel at a same time or around thereto, the transparent panel acting as a transmission layer that transmits the light emitted from the light-emitting layers and having a plurality of recesses forming a plurality of total reflection surfaces capable of totally reflecting at least a part of the light radiated from the light-emitting layers in the direction of emission of the light-emitting layers; and
joining the transparent panel and the substrate together in the position that protrusions between the recesses of the transparent panel substantially corresponds to the light-emitting layers so as to be in optically close contact with the light-emitting layers. - View Dependent Claims (17, 18)
