In this deposition method, when the depth of the concave portion 301 is greater than the deposition thickness of the common layer 600, the common layer 600 will break at the concave portion 301 and cannot cover the concave portion 301.
Therefore, outside water and oxygen W can invade from the concave portion 301 and contact the organic light-emitting layer of the organic light-emitting display panel, and then cause the pixels to shrink inward and form black spots during the display process of the organic light-emitting display panel, which affects the organic light-emitting display panel. display performance

Abstract
The present invention discloses a method for manufacturing an organic light-emitting display panel. The method for manufacturing an organic light-emitting display panel includes the following steps: providing a substrate, and the substrate includes a plurality of light-emitting regions and a non-conductive layer between the plurality of light-emitting regions. A light-emitting area, and a pixel definition layer is formed on one side of the substrate, and the pixel definition layer is formed in the non-light-emitting area; a spacer is formed on the side of the pixel definition layer away from the substrate; forming an organic light-emitting layer in the light-emitting region above; and depositing a common layer on the side of the pixel definition layer and the organic light-emitting layer away from the substrate, the common layer covering the spacer; wherein, the A first included angle formed between the deposition direction of the common layer and the first plane where the substrate is located is greater than 0 degrees and less than 90 degrees.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing an organic light-emitting display panel. Background technique [0002] Compared with traditional liquid crystal displays, organic light-emitting display panels have the advantages of fast response, high contrast, brilliant colors, higher resistance to high and low extreme temperatures, and thinner and lighter weight. Therefore, they have gradually become the mainstream technology in the display field and are widely used in mobile phones, Tablet PCs, TVs, virtual reality, and more. [0003] During the manufacturing process of existing organic light-emitting display panels, organic materials are usually deposited on the substrate by using a high-precision metal mask (FMM), and the high-precision metal mask is placed at intervals during use. On the object (PS), the edge of the opening of the high-precision metal mask will damage the spacer due to materia...
