Abstract

The invention provides a display panel and a preparation method thereof and a display device. The display panel comprises a substrate and at least one light-emitting device arranged on one side of the substrate, wherein at least one light-emitting device comprises a target light-emitting device, and the target light-emitting device comprises an anode, a light-emitting layer and a cathode which are sequentially arranged; an organic self-assembly film for improving the hydrophilicity of the surface of the anode into hydrophobicity is arranged between the anode and the light-emitting layer, a hole function layer is arranged between the organic self-assembly film and the light-emitting layer, and the hole function layer comprises at least one of a hole injection layer and a hole transmission layer. The organic self-assembly film is arranged on the surface of the anode, so that the surface of the anode is changed from the original hydrophilicity to hydrophobicity, the subsequent deposition of a hole function layer is more compact and uniform, and the injection and transmission performance of carriers in the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and It is considered by the industry to be the display device with the most potential for development due to its advantages such as large-area full-color display. [0003] OLED devices generally include: a substrate, an anode disposed on the substrate, a hole injection layer disposed on the anode, a hole transport layer disposed on the hole injection layer, a light emitting layer disposed on the hole transport layer, a An electron transport layer on the light emitting layer, an electron injection layer on the electron tr...
