Abstract

The invention discloses a spacer, an organic light emitting display panel, a manufacturing method and a display device. The manufacturing method of the spacer comprises the following steps: firstly, forming a plurality of independent spacer patterns by adopting a solidifiable material on a substrate base-plate by virtue of a coating process; and solidifying all spacer patterns. Compared with an existing method of manufacturing the spacers through composition processes such as exposure, developing, the manufacturing method is simpler in manufacturing process.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a spacer, an organic electroluminescence display panel, a manufacturing method and a display device. Background technique [0002] Among existing display panels, organic electroluminescent display panels (Organic Electroluminescent Display, OLED) have gradually become the mainstream in the display field due to their low power consumption, high color saturation, wide viewing angle and other characteristics. [0003] In the production process of the existing organic electroluminescent display panel, when the array substrate formed with the organic electroluminescent structure and the packaging cover plate are subjected to the box-to-box process, in order to avoid damage to each film in the organic electroluminescent display panel Layers are damaged, and a spacer needs to be provided between the organic electroluminescent structure and the packaging cover plate. At present, spacer...
