Abstract

The embodiment of the invention provides a display panel, a preparation method and display equipment. The display panel comprises a substrate, a pixel defining structure and a plurality of sub-pixel opening areas, wherein the pixel defining structure and the sub-pixel opening areas are arranged on the substrate, and the pixel defining structure comprises a plurality of first pixel defining structures and a plurality of second pixel defining structures. The gradient angle of a second pixel defining structure is set to be larger than that of a first pixel defining structure, so that the second pixel defining structure is used for separating light-emitting layers of sub-pixels of different colors in adjacent sub-pixel opening areas; therefore, the phenomenon that the sub-pixels with differentcolors are communicated is avoided, the phenomenon of pixel light leakage of the display panel is avoided, and the display quality of the display panel is improved.

Description

technical field [0001] The present application relates to the technical field of display devices, and in particular, the present application relates to a display panel, a manufacturing method, and a display device. Background technique [0002] At present, organic light-emitting diode (OLED) display has the advantages of thinness, wide viewing angle, active light emission, fast response speed, low energy consumption, low driving voltage, high luminous efficiency, and flexible display, etc. Widespread concern. The OLED display panel includes an array substrate and an organic light emitting device, and the organic light emitting device includes an anode, an organic light emitting layer, a cathode, and the like. The array substrate includes a driving circuit formed using thin film transistors (TFTs). In order to form the organic light-emitting layer, it is necessary to form a pixel defining layer (Pixel Define Layer, PDL) on the array substrate to separate each pixel area, so...
