Title:
DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/238621
Kind Code:
A1
Abstract:
Provided are a display panel and a manufacturing method therefor, and a display apparatus. The display panel has a plurality of sub-pixels, and comprises a substrate, pixel definition layers arranged on the substrate, a light-emitting device, and a color film layer, wherein there are M pixel definition layers, and M is a positive integer greater than or equal to 2; an mth pixel definition layer covers the surface of an (m-1)th pixel definition layer; and the refractive index nm-1 of the (m-1)th pixel definition layer is greater than the refractive index nm of the mth pixel definition layer, and 2 ≤ m ≤ M. When an incident angle, at an interface of adjacent pixel definition layers, of light emitted by a light-emitting layer to pixel definition layers is greater than a critical angle, the light is totally reflected, so that the light is limited within the pixel definition layers, thereby reducing light entering adjacent sub-pixels, reducing the problems of light crosstalk, poor viewing angle, color separation, etc., and improving the display effect.
