Abstract

The invention provides an organic light-emitting display panel, a preparation method thereof and a display device, and the display panel comprises: a pixel limiting layer which comprises a hollow region for limiting a preparation region of an organic light-emitting layer; and a supporting columns arranged on the surface of the pixel limiting layer, wherein the surface, deviating from the pixel limiting layer, of the supporting column comprises a wear-resistant material. The supporting column comprises the wear-resistant material, so that the wear resistance of the supporting column is improved, the supporting column is effectively prevented from being scratched by the mask plate, the film forming effect of the flexible packaging film layer is ensured, the packaging reliability of a productis improved, and the service life of the product is prolonged.

Description

Technical field [0001] The present invention relates to the field of organic light-emitting display technology, in particular to an organic light-emitting display panel, a method for preparing an organic light-emitting display panel, and a display device including the organic light-emitting display panel. Background technique [0002] Organic Light Emitting Diode (OLED, Organic Light Emitting Diode) has become an important display technology due to its characteristics of lightness and thinness, large viewing angle, and significant power saving. [0003] Evaporation is a key manufacturing process for OLEDs. In the OLED manufacturing process, coatings of different shapes need to be vapor-deposited on the substrate. In order to vapor-deposit coatings of different shapes, a mask is required to assist in preparation. In order to ensure the distance between the mask plate and the substrate, support pillars are needed to support the mask plate. However, during the evaporation process, th...
