Abstract

The present invention provides a display device, an array substrate and a manufacturing method thereof, comprising: providing a substrate, the substrate including a substrate and a TFT array on the surface of the substrate; forming a first TFT array on the surface of the substrate An electrode layer; forming a mask with a plurality of first electrode patterns and at least one filling pattern between the first electrode patterns on the surface of the first electrode layer; etching the first electrode layer with the mask A plurality of first electrodes are formed, wherein, during the etching process, part or all of the first electrode layer covered by the filling pattern is etched. The present invention increases the pattern density of the first electrode pattern through the filling pattern between the first electrode patterns, so as to avoid the problem of over-etching or uneven etching of the first electrode during the etching process of the first electrode, and solve the problem caused by This causes defects such as dark spots on the display screen.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to an array substrate, a manufacturing method thereof, and a display device including the array substrate. Background technique [0002] The existing OLED (Organic Light-Emitting Diode, organic laser display) display includes a plurality of OLED pixel units, and each OLED pixel unit includes a first electrode, a second electrode, and an electrode located between the first electrode and the second electrode. The organic light-emitting layer, wherein the first electrode is an anode and the second electrode is a cathode, the display device inputs electrons to the organic light-emitting layer through the cathode and absorbs electrons from the organic light-emitting layer through the anode to excite the organic light-emitting layer to emit light. [0003] In the prior art, when making the first electrode, the first electrode layer covering the entire substrate is...
