Display panel, manufacturing method thereof and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel is provided with a plurality of pixel regions, and each pixel region consists of a plurality of subpixels of the same color. The display panel comprises an array substrate and a display layer, wherein the array substrate comprises a base layer and an array layer; the display layer is arranged on the side, away from the base layer, of the array layer; and the display layer comprises an anode metal layer, a first pixel defining layer, a second pixel defining layer and organic light-emitting layers; the anode metal layer is provided with a plurality of anodes, and one subpixel comprises one anode; the first pixel defining layer is arranged on the side, away from the array layer, ofthe anode metal layer, the first pixel defining layer is provided with a plurality of first openings exposing the anodes, and one pixel region comprises one first opening; the second pixel defining layer is prepared from a lyophobic material and comprises first defining parts on the first pixel defining layer and second defining parts positioned inside the first openings, the second defining partsare used for partitioning the first openings into a plurality of second openings, and one subpixel comprises one second opening; and the organic light-emitting layers are arranged inside each secondopening. The problem of color crosstalk for the display panel is solved.

Description

technical field [0001] The present invention relates to the technical field of semiconductors, and more particularly, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is also called organic electro-laser display, organic light-emitting semiconductor. OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast ratio, low power consumption, and extremely high response speed. It is widely used in mobile phones, digital cameras, notebook computers, car audio, and televisions. [0003] In OLED display panel technology, since the light-emitting layer is produced by printing process, it is difficult to realize the preparation of high-resolution display panel by adopting the traditional RGB arrangement of pixel structure due to the influence of equipment precision and droplet size of the material of the ligh...

Problems solved by technology

[0003] In the technology of OLED display panel, since the light-emitting layer is made by printing process, it is difficult to realize the preparation of high-resolution display panel by adopting the traditional RGB pixel structure, which is affected by the precision of the equipment and the droplet size of the material of the light-emitting layer.

In the prior art, the sub-pixels of the same color in adjacent pixels share the openings on the mask, and the resolution is improved through different pixel designs. figure 1 It is a schematic top view of a display panel in the prior art, such as figure 1 As shown, in this technology, since the light-emitting devices of some sub-pixels sp' of two adjacent pixels 1P' and 2P' are connected together, when two pixels 1P' and 2P' are given different voltages, adjacent The mutual influence between the sub-pixels 1sp' and 2sp' of the same color in the pixel produces color crosstalk and affects the display effect of the display panel
