Problems solved by technology

However, when using a pixel structure in which sub-pixels of the same color are gathered together, the functional layers of the sub-pixels in the same ink deposition area are integrated, which easily causes lateral leakage current, which in turn affects the contrast and display effect of the entire display panel.

Abstract

The invention relates to a display panel, a display device and a manufacturing method thereof. The display panel includes a substrate, a sub-pixel unit arranged on the substrate, and a first pixel defining layer for defining adjacent sub-pixel units of the same color, wherein a filling groove is provided on the first pixel definition, and the filling groove is filled Has a lyophobic layer. Due to the arrangement of the lyophobic layer in the filling groove of the display panel, the thickness of the light-emitting functional layer corresponding to the region above the lyophobic layer is significantly reduced or cut off, thereby effectively reducing the generation of lateral leakage current and improving the display effect of the display panel. and resolution.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a manufacturing method thereof. Background technique [0002] Organic electroluminescent diodes (OLEDs) have the advantages of self-illumination, fast response, wide viewing angle, high brightness, and thinness. Long and other advantages are the two main directions of display device research at present. The process of manufacturing OLED displays and QLED displays by solution processing has the advantages of low cost, high productivity, and easy realization of large sizes, and is an important direction for the development of display technology in the future. At the same time, printing technology is considered to be the most effective way to realize OLED and QLED low-cost and large-area full-color display. [0003] At present, in the printing process, the deposition area of ​​ink can be enlarged by concentrating sub-pixels of the sam...
