Abstract

A method for fabricating a COA array substrate, an array substrate and a display device are provided. The COA array substrate includes a photoresist layer disposed on a protection layer, wherein a color filter receiving hole is formed in the photoresist layer, and a color filter layer is formed in the color filter receiving hole, an entire surface of the photoresist layer is flushed with an entire surface of the color filter layer such that the photoresist layer functions as the planarized layer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A COA array substrate, comprising a photoresist layer disposed on a protection layer, wherein a color filter receiving hole is formed in the photoresist layer, and a color filter layer is formed in the color filter receiving hole, an entire surface of the photoresist layer is flushed with an entire surface of the color filter layer such that the photoresist layer functions as the planarized layer. 
     
     
         2 . The COA array substrate of  claim 1 , wherein the COA array substrate is an OLED array substrate, a via hole penetrating through the photoresist layer and the protection layer is disposed on the COA array substrate, an OLED anode is electrically connected to a drain electrode of a TFT on the OLED substrate through the via hole. 
     
     
         3 . The COA array substrate of  claim 1 , wherein the COA array substrate is a TFT-LCD array substrate, a via hole penetrating through the photoresist layer and the protection layer is disposed on the COA array substrate, a pixel electrode is electrically connected to a drain electrode of a TFT on the TFT-LCD substrate through the via hole. 
     
     
         4 . A display device comprising the COA array substrate of  claim 1 .
