Abstract

The invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a substrate, the substrate comprises a plurality of light-emitting areas, and the display panel further comprises a pixel blocking layer. Each light-emitting area comprises a first electrode, a functional layer and a quantum dot layer which are sequentially located on the substrate. The pixel barrier layer comprises an opening area and a dam, and the dam is located in the adjacent light-emitting area and surrounds the first electrode. According to the display panel, the first electrode, the functional layer and the quantum dot layer are sequentially stacked on the substrate in the light-emitting area of the display panel, and the first electrode is surrounded by the pixel barrier layer, so that in the actual manufacturing process, the limitation of the pixel light-emitting area can be completed by adopting a graphical process, and then the first electrode and the functional layer are manufactured at the corresponding positions of the light-emitting area; in this way, dry etching possibly involved in the patterning process does not affect the first electrode and the functional layer at the corresponding position of the light-emitting area, and then red, green and blue three-color quantum dot pixels can form the optimal device structure.

Description

technical field [0001] The present application relates to the field of display technology, and specifically relates to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Active-matrix organic light-emitting diodes (Active-matrix organic light-emitting diodes; AMOLEDs) were once considered to be a next-generation display device capable of replacing liquid crystal displays (LCDs). However, with the improvement of consumers' consumption level, high-resolution products have become the key development direction of display products. At present, high-resolution AMOLED products are facing problems of high technical difficulty, low product yield, and high commodity prices. [0003] On the other hand, with the in-depth development of quantum dot technology, the research on quantum dot light-emitting diodes (Quantum DotLight Emitting Diodes; QLED) has been deepened, and the quantum efficiency has been continuously improved, which has ba...
