Abstract

The invention relates to a display substrate and a manufacturing method thereof, a display panel and a display device, and belongs to the field of displays. The display substrate is provided with a plurality of pixel areas. The display substrate comprises a cover plate, a color filter layer, retaining walls and a plurality of quantum dot films, wherein the color filter layer is located on the cover plate and corresponds to the pixel areas, the retaining walls are located on the cover plate and located between the adjacent pixel areas, the quantum dot films are located on the color filter layer, and the quantum dot films correspond to at least part of the pixel areas. The retaining wall is made of at least one of a photochromic material or a filtering material. When encountering light emitted from the interior of the display device, the photochromic material is converted into colors capable of blocking the light, and the light filtering material can filter the light of each color, so that shading is realized. When the material is used for manufacturing the retaining wall, the retaining wall can be manufactured to be thinner, so that the thickness of the retaining wall is smaller than that of the retaining wall formed by the black matrix and the protective layer, and the thickness of the display device can be reduced.

Description

Technical field [0001] The present disclosure relates to the field of displays, in particular to a display substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] Quantum Dot Organic Light-Emitting Display (English: Quantum Dot Organic Light-Emitting Display, referred to as: QD-OLED) uses blue light as a light source, and red quantum dots (English: Quantum Dot Red) are arranged in the red pixel unit and the green pixel unit of the display panel respectively. , Abbreviation: QD-R) film and green quantum dot (English: Quantum DotGreen, abbreviation: QD-G) film, red quantum dot film and green quantum dot film can respectively convert blue light into red light and green light. [0003] Exemplarily, the QD-OLED display panel may include a QD-OLED array substrate, a quantum dot film located on the QD-OLED array substrate, a color filter layer and a barrier wall, and the color filter layer and barrier wall. The cover plate, the co...
