Title:
QUANTUM DOT DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159707
Kind Code:
A1
Abstract:
A quantum dot display panel and a manufacturing method therefor, and a display device, which relate to the technical field of displays. A quantum dot light-emitting layer (40) in a traditional method is transferred from one side of a color film cover plate (60) to one side of an array substrate (10), thereby reducing the impact of alignment deviation on the quantum dot light-emitting layer (40), which alignment deviation is caused by a later alignment process between a cover plate and the array substrate (10). Moreover, since a pixel definition area (31) is presented as a closed shape formed inside an encapsulation layer (30), an encapsulation film layer can be omitted from the color film cover plate (60) of the quantum dot display panel, thereby achieving the aim of simplifying the process.
