发明名称 LIGHT EMITTING DEVICE
摘要 A light emitting element includes a reflective layer disposed in a substrate, a first electrode disposed through the reflective layer, a second electrode having translucent reflectivity, a plurality of organic material layers including a light emitting layer disposed between the first electrode and the second electrode, and a light emitting region defined by the first electrode, the second electrode, and the light emitting layer. A first organic material layer of the plurality of organic material layers has a first layer thickness in a first sub region within the light emitting region and has a second layer thickness, which is different from the first layer thickness, in a second sub region within the light emitting region.
