Abstract

The invention provides a display panel and a preparation method of the display panel. The display panel comprises an array substrate, a pixel definition layer and spacing columns, the pixel definitionlayer is arranged on the array substrate, the spacing columns are arranged on the pixel definition layer, each spacing column comprises a bottom surface and a top surface, the sectional area of eachtop surface is smaller than that of each bottom surface, and the horizontal distances from the top surfaces to the bottom surfaces and the centers of the spacing columns to the side surfaces are gradually increased. During photoetching, openings are formed in the positions, corresponding to the spacing columns, of the mask plate, the mask plate is accurately positioned through the spacing columns,and the photoetching precision and the display effect of the display panel are guaranteed.

Description

technical field [0001] The disclosure relates to the field of display technology, and in particular to a display panel and a method for preparing the display panel. Background technique [0002] Compared with liquid crystal display devices, organic electroluminescent display devices (Organic Light-Emitting Device, OLED) have advantages such as self-luminescence, fast response, thinness, etc., and have become an emerging technology in the display field. [0003] In the manufacturing process of the display panel, the fine metal mask plate evaporation technology (fine metalmask, FMM) will be used. The organic material evaporation process refers to the use of the FMM process to evaporate organic light-emitting materials in specific pixels on the backplane. The process of forming a specific light-emitting device can realize R / G / B full-color OLED. In the existing FMM technology of the display panel, it is usually formed by splicing a plurality of sub-masks. It requires high prec...
