Title:
DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/222436
Kind Code:
A1
Abstract:
The present application relates to the technical field of display and discloses a display panel and a manufacturing method therefor, and a display device. The display panel comprises: a substrate, an insulating layer, auxiliary electrodes, a light-emitting layer, and a cathode layer. Each auxiliary electrode and the cathode layer are overlapped by means of a first via hole in the insulating layer, and the opening of the first via hole is in the shape of a polygon, so that the light-emitting layer breaks at each edge of the opening to ensure that none of the side walls of the auxiliary electrode located in the first via hole has the light-emitting layer attached thereon, thereby increasing the overlapping area between the auxiliary electrode and the cathode layer, achieving effective overlapping between the cathode layer and the auxiliary electrode, and thus improving display effect of the display panel.
