Abstract
The present application provides an array substrate and a display device. By placing a first shielding electrode between the data line and the common electrode arranged opposite to each other, the first shielding electrode is connected to a DC voltage signal, so that a data voltage signal of the data line does not affect a signal of the common electrode. This prevents coupling capacitance between the common electrode and the data line, and prevents poor display quality like screen flickering.

An array substrate, comprising:
- a substrate;
- a gate insulating layer disposed on the substrate;
- a data line disposed on the gate insulating layer;
- a first passivation layer disposed on the gate insulating layer and covering the data line;
- a first shielding electrode disposed on the first passivation layer, wherein the first shielding electrode is connected to a direct current (DC) voltage signal output terminal;
- a second passivation layer disposed on the first passivation layer and covering the first shielding electrode;
- a common electrode disposed on the second passivation layer, wherein a portion of the common electrode overlaps with the data line and the first shielding electrode;
- and
- a pixel electrode arranged in a same layer as the common electrode or arranged in stacked relation with the common electrode, and the pixel electrode is electrically insulated from the common electrode.
