Abstract
Disclosed herein are a light-emitting device including a first electrode, a first functional layer, a patterned insulating layer, a patterned second electrode, a patterned second functional layer, and a light-emitting layer, and a methods of manufacturing the same. In the present disclosure, an orthographic projection of the patterned second electrode on the first functional layer is located within an orthographic projection of the patterned insulating layer on the first functional layer, so as to avoid the contact of the patterned second functional layer with the first functional layer, and avoid a current leakage of the light-emitting device.
Claims20
A light-emitting device comprising:
- a first electrode;
- a first functional layer disposed on the first electrode;
- a patterned insulating layer disposed on the first functional layer and at least partially exposing the first functional layer;
