Abstract
An electroluminescence display having enhanced display quality by preventing external light from being reflected is disclosed. An electroluminescence display according to the present disclosure comprises: a substrate including an emission area and a non-emission area; a partially transparent layer on the substrate; a transparent layer on the partially transparent layer; a signal line in the non-emission area on the transparent layer; a passivation layer covering the signal line; a planarization layer on the passivation layer; and a light emitting element including a first electrode, an emission layer and a second electrode in the emission area on the planarization layer.
Claims16
An electroluminescence display comprising:
- a substrate including an emission area and a non-emission area;
- a partially transparent layer on the substrate, the partially transparent layer having a first optical transmittance;
- a transparent layer on the partially transparent layer, the transparent layer having a second optical transmittance that is greater than the first optical transmittance of the partially transparent layer;
- a signal line on the transparent layer in the non-emission area;
- a passivation layer covering the signal line;
- a planarization layer on the passivation layer;
- and
- a light emitting element on the planarization layer in the emission area, the light emitting element including a first electrode, an emission layer on the first electrode, and a second electrode on the emission layer,
- wherein the transparent layer has a thickness in which a first phase of a first reflected light from the partially transparent layer and a second phase of a second reflected light from the signal line are opposite in phase from each other, and
- wherein the first phase of a first reflected light from the partially transparent layer and a third phase of a third reflected light from the second electrode are opposite in phase from each other.
