Display panel, preparation method thereof and display device

Abstract

The invention provides a display panel, a preparation method thereof and a display device. The display panel comprises a substrate, a pixel limiting layer and a plurality of supporting columns, wherein the pixel defining layer is formed on the substrate and is defined to form a plurality of pixel areas; the supporting columns are arranged on the surface of the side, away from the substrate, of the pixel limiting layer and located between the adjacent pixel areas; wherein an avoiding part is formed on the supporting column, so that the opening edge of the mask plate is suspended through the avoiding part. The display panel can effectively guarantee the flatness of the surface of the side, deviating from the substrate, of the supporting column, improves the reliability of product packaging, and reduces the occurrence probability of abnormal product display.

Description

technical field

[0001] The invention 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 emission diode (OLED) display devices are widely favored in the display technology industry due to their luminous effect and the advantages of thinness, flexibility, and high color contrast in display.

[0003] Currently, see figure 1 , figure 1 It is a schematic diagram of the structure of vapor-depositing organic materials through fine metal masks in the prior art; in the preparation process of OLED organic light-emitting layer, organic materials need to be vapor-deposited on the substrate prepared with thin-film transistors through fine metal masks , to form R / G / B organic light-emitting layers respectively. Among them, in the evaporation chamber, in order to prevent the fine metal mask from directly contacting the substrate and scratching the substrate film la...
