Abstract
Disclosed in the present application are a light-emitting device and a manufacturing method therefor, and a display panel. The manufacturing method for a light-emitting device comprises the following steps: providing a first device plate; coating the first device plate with a metal oxide mixed solution; performing first annealing treatment on the metal oxide mixed solution at a first preset temperature; performing secondary annealing treatment on the metal oxide mixed solution at a second preset temperature; and forming a second device plate on a surface of a second electron transport layer that is away from a first electron transport layer.
Claims18
A method of manufacturing a light-emitting device comprising:
- providing a first device plate;
- coating a metal oxide mixed solution on the first device plate;
- performing a first annealing treatment on the metal oxide mixed solution at a first preset temperature to form a first electron transport layer;
- performing a second annealing treatment on the metal oxide mixed solution at a second preset temperature to form a second electron transport layer, the second electron transport layer being disposed on one side of the first electron transport layer away from the first device plate, and the second preset temperature being greater than the first preset temperature;
- and
- forming a second device plate on one side of the second electron transport layer away from the first electron transport layer.
