Abstract
Provided is a pixel defining layer of an organic light-emitting diode display panel. The pixel defining layer includes: an insulating transparent cladding layer; and a reflecting layer in the transparent cladding layer, wherein the reflecting layer is configured to reflect light emitted from a light-emitting layer of the organic light-emitting diode display panel. Organic light-emitting diode display panels and methods for manufacturing an organic light-emitting diode display panel are also provided.
Claims18
