Problems solved by technology

When using the plasma vapor deposition process to prepare the inorganic pixel defining layer, the substances or gases in the preparation process will chemically react with the etching solution remaining on the planarization layer, resulting in holes in the planarization layer, causing the edge of the anode to collapse, and then affecting the performance of the OLED device.
[0004] In summary, the preparation process of the pixel defining layer in the prior art is easy to cause damage to the planarization layer, causing the edge of the anode to collapse and affecting the stability of the product.

Abstract

The invention discloses an array substrate, a display panel and a display device, which are used for reducing damage to a substrate during the fabrication process of a pixel defining layer and preventing an edge of an electrode layer from being collapsed so as to further improve the working stability of a product. The embodiment of the invention provides the array substrate. The array substrate comprises a substrate, electrode layers, block-up layers and pixel defining layers, wherein electrode layers are arranged on the substrate and are arranged in an array way, the block-up layers are arranged on the substrate and are isolated with the electrode layers at intervals, the pixel defining layers are arranged on the block-up layers, and the electrode layers are in contact with the block-up layers.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an array substrate, a display panel and a display device. Background technique [0002] Organic electroluminescent displays have the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright colors, light and thin, etc. Organic electroluminescent display technology has become an important display technology. [0003] For Organic Light Emitting Diode (OLED) or Polymer Light Emitting Diode (PLED) organic electroluminescent devices, there are two methods of forming organic thin films: vacuum evaporation and solution process. The vacuum evaporation method is suitable for small organic molecules. Its characteristics The formation of organic films does not require solvents, and the film thickness is uniform, but the equipment investment is large, the material utilization rate is low, and it is not suitable for the production of large-sca...
