Abstract
The present invention relates to a display panel. The material of the first electron blocking layer located in the first sub-pixel area and the second sub-pixel area of the present invention is the same, so that the same mask can be used in the same evaporation chamber to fabricate a first electron blocking layer in the first sub-pixel area and the second sub-pixel area at the same time, thereby saving production costs and reducing fabrication difficulty.
Claims11
A display panel, comprising a plurality of spaced sub-pixel areas and a blocking region located between the plurality of sub-pixel areas, wherein each of the plurality of sub-pixel areas comprises a first sub-pixel area and a second sub-pixel area;
- and
- wherein the display panel comprises:
- a substrate;
- and
- a light-emitting layer arranged on a side of the substrate, wherein the light-emitting layer comprises:
- a first electron blocking layer arranged on the substrate and located in the first sub-pixel area, the second sub-pixel area and the blocking region between the first sub-pixel area and the second sub-pixel area;
- wherein a hole mobility of a material of the first electron blocking layer located in the first sub-pixel area is greater than a hole mobility of the material of at least a part of the first electron blocking layer located in the blocking region;
- and/or
- a hole mobility of the material of the first electron blocking layer located in the second sub-pixel area is greater than a hole mobility of the material of at least a part of the first electron blocking layer located in the blocking region.
