Abstract

The invention provides a display backboard, a display panel and a manufacturing method thereof, and a display device. The display backboard comprises a substrate, a thin film transistor array layer arranged on one surface of the substrate, a planarization layer arranged on one side, away from the substrate, of the thin film transistor array layer, and a pixel defining layer arranged on a surface,away from the substrate, of the planarization layer. The pixel defining layer comprises a first pixel defining layer, a plurality of first openings are defined by the first pixel defining layer, and reflecting layers are arranged on at least parts of side walls of the first openings. The display backboard does not easily generate lateral light leaking, production cost is low, a utilization rate oflight emitted by a light-emitting element is high, display brightness is high too, a display effect is good and the backboard, the panel, the method and the device are particularly suitable for small-size display in an AR field and the like.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display backplane, a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, display panels are gradually tending to realize smaller-sized displays (such as AR fields, etc.), and this trend will undoubtedly continue to accelerate in the near future. It is foreseeable that for smaller-sized display technologies, international first-line customers will demand products with higher brightness in the future. However, in the related art, the display brightness of the display backplane is still low. [0003] Therefore, the related technologies of the existing display backplane still need to be improved. Contents of the invention [0004] The present invention is accomplished based on the following findings of the inventors: [0005] In related technologies, most of the light emitted by the light-emitting elements in...
