Title:
PIXEL DEFINING LAYER, MANUFACTURING METHOD THEREFOR, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2020/248979
Kind Code:
A1
Abstract:
A pixel defining layer, a manufacturing method therefor, and a display panel. The pixel defining layer (10) comprises: a first sub-defining layer (11), a light absorbing layer (12), and a second sub-defining layer (13) sequentially stacked on a substrate (21). The light absorbing layer (12) is used for absorbing light for exposing the first sub-defining layer (11). An orthographic projection of the light absorbing layer (12) on the substrate (21) covers the outer edge of an orthographic projection of the first sub-defining layer (11) on the substrate (21) away from the surface of the substrate (21). By providing the light absorbing layer, the problem of trailing or over-etching of the pixel defining layer caused by light scattering during the exposure process can be solved.
