Abstract:
The present disclosure provides a light-emitting apparatus including a plurality of types of light-emitting pixels, each of the light-emitting pixels including a reflective electrode, an electrode-protective layer, an organic compound layer containing a light-emitting layer, and a light-output electrode in this order and having a resonator structure, wherein at least one type of the plurality of types of light-emitting pixels is a light-emitting pixel having a greater interference order than other types of light-emitting pixels, and the electrode-protective layer of the light-emitting pixel having the greater interference order has a greater layer thickness than the electrode-protective layers of the other types of light-emitting pixels.
