Abstract

A display panel, comprising: a plurality of first light emitting layers, a plurality of second light emitting layers, a plurality of third light emitting layers, and a pixel defining layer, comprising: a plurality of first openings covered by corresponding first light emitting layers, composed of A plurality of second openings covered by corresponding second light emitting layers, and a plurality of third openings covered by corresponding third light emitting layers. The first and second light-emitting layers are alternately arranged in the first direction and the second direction crossing the first direction, and the third light-emitting layers are scattered between the first light-emitting layers and the second light-emitting layers. Each of the first and second light-emitting layers includes two corners facing each other in the first direction and two corners facing each other in the second direction, each corner having a The edges are chamfered so that the respective first and second light-emitting layers do not overlap each other.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a method for manufacturing a display panel and a set of mask plates for manufacturing a display panel. Background technique [0002] Evaporation of organic light-emitting materials is a key link in the manufacturing process of organic light-emitting diode (OLED) display panels. During the evaporation process, a perforated ultra-fine metal mask (FMM) is used to obtain high-resolution sub-pixel patterns. As pixel density becomes higher and higher, ensuring the yield of OLED display panels becomes a challenge. Contents of the invention [0003] It would be advantageous to have a solution that alleviates, alleviates or even eliminates one or more of the above problems. [0004] According to a first aspect of the present invention, there is provided a display panel, comprising: a plurality of first light-emitting layers configured to emit light of a first...
