Abstract
The present disclosure discloses a light-emitting device, a preparation method therefor, and a display apparatus. A first and a second passivation protection functional layer are disposed between a first electrode and a light-emitting layer and between a second electrode and the light-emitting layer, and laser damage thresholds of the first and the second passivation protection functional layer are both greater than a laser damage threshold of the light-emitting layer.
Claims20
A light-emitting device comprising:
- a first electrode;
- a first passivation protection functional layer;
- a light-emitting layer;
- a second passivation protection functional layer;
- and
- a second electrode;
- Wherein, the light-emitting layer is disposed between the first electrode and the second electrode, the first passivation protection functional layer is disposed between the first electrode and the light-emitting layer, the second passivation protection functional layer is disposed between the second electrode and the light-emitting layer, and a laser damage threshold of the first passivation protection functional layer and a laser damage threshold of the second passivation protection functional layer are both greater than a laser damage threshold of the light-emitting layer.

A preparation method for a light-emitting device comprising the following steps:
- forming a first passivation protection functional layer on a side of the first electrode;
- forming a light-emitting layer on a side of the first passivation protection functional layer away from the first electrode, wherein a laser damage threshold of the first passivation protection functional layer is greater than a laser damage threshold of the light-emitting layer;
- forming a second passivation protection functional layer on a side of the light-emitting layer away from the first passivation protection functional layer, wherein a laser damage threshold of the second passivation protection functional layer is greater than that of the light-emitting layer;
- and
- forming a second electrode on a side of the second passivation protection functional layer away from the light-emitting layer.
