Title:
DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/169648
Kind Code:
A1
Abstract:
Provided are a display panel and a manufacturing method therefor, and a display device, which are used for realizing cathode isolation. The display panel comprises: a substrate (1), a pixel defining layer (2) located on the substrate, and a cathode isolation structure (3) located on the pixel defining layer (2). The cathode isolation structure (3) comprises at least a first isolation sub-layer (4) and a second isolation sub-layer (5) located between the pixel defining layer (2) and the first isolation sub-layer (4), the cross section of the second isolation sub-layer (5) is smaller than that of the first isolation sub-layer (4), and an orthographic projection, on the substrate (1), of the second isolation sub-layer (5) falls within an orthographic projection range, on the substrate, of the first isolation sub-layer (4).
