Emitter, manufacturing method and manufacturing apparatus thereof, electro-optical apparatus and electronic apparatus

摘要

An emitter has a plurality of type of light-emitting units with different changes in emission chracteristics over time. In addition, the emitter includes a deterioration adjustment device which adjusts the deterioration of the emission characteristics over time in a predetermined type of light-emitting unit. The light-emitting units respectvely include a light-emittig unit layer and a donor which supplies positive holes to the light-emiting layer, and deterioration adjustment device may be the hole donor in which the thickness is adjustadle based on the deterioration in emission characteristics over time in the predetermined type of light-emitting unit.
