Abstract

The present invention relates to an array substrate, a manufacturing method thereof, and a display device. The array substrate includes: gate lines, common electrode lines, and data lines disposed on a substrate; The first spacer layer between the common electrode line and the data line, the first spacer layer extends to at least one side in the width direction of the data line for a predetermined length; and / or is arranged in the overlapping area of ​​the gate line and the data line, and is located A second spacer layer between the gate line and the data line, the second spacer layer extends to at least one side in the width direction of the data line for a predetermined length. By setting the first spacer layer and / or the second spacer layer, when exposing the data line metal layer, the data caused by the difference in light reflectance between the common electrode layer metal and / or the gate line layer metal and the data line layer metal can be reduced. The difference in line width can improve the uniformity of data line width, reduce the risk of data line disconnection, and improve product yield.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular, to an array substrate, a display device and a manufacturing method of the array substrate. Background technique

[0002] TFT (Thin Film Field Effect Transistor) driven display devices are currently the mainstream technology in the display field. A thin film field effect transistor display usually includes a color filter substrate and a TFT array substrate. The TFT array substrate includes a plurality of pixel units, and each pixel unit corresponds to a TFT. When a certain voltage is applied to the gate of the TFT, when the gate voltage reaches the threshold voltage, the channel is turned on (that is, the active layer is turned on), thereby turning on the source and drain, and the signal in the data line is transmitted to the TFT through the source. The drain, and further controls the pixel electrode electrically connected to the drain. The voltage difference between the ...
