Abstract
An emitter has a plurality of types of light-emitting units with different changes in emission characteristics 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 respectively include a light-emitting layer and a hole donor which supplies positive holes to the light-emitting layer, and the deterioration adjustment device may be the hole donor in which the thickness is adjusted based on the deterioration in emission characteristics over time in the predetermined type of light-emitting unit.
Claims3
A manufacturing apparatus of an emitter having a plurality of light-emitting units with different changes in emission characteristics over time, the apparatus comprising:
- a control device which adjusts deterioration of the emission characteristics over time in a predetermined light-emitting unit;
- and
- a discharge device which discharges a liquid containing a hole donor material,
- wherein the light-emitting units respectively have a light-emitting layer and a hole donor which supplies positive holes to the light-emitting layer,
- wherein the discharge device forms the hole donor by discharging the liquid containing the hole donor material, and
- wherein the control device adjusts at least one of a weight or a number of drops of the liquid discharged from the discharge system based on the light-emitting unit among the plurality of light-emitting units that has the largest degree of deterioration of emission characteristics over time.
