Abstract
The present disclosure proposes a TFT array substrate and a method of forming the same. The TFT array substrate includes a substrate, a semi-conductor layer, a pixel electrode on the substrate so to be on the same layer as the semi-conductor layer, a gate insulating layer, a gate electrode, an ILD layer on the substrate so to cover the gate insulating layer, gate electrode and pixel electrode, a source electrode on the ILD layer and connected to the semi-conductor layer, and a drain electrode on the ILD layer and connected to the semi-conductor layer and pixel electrode. The TFT array substrate can prevent etching of the metal oxide by an etching solution. The TFT array substrate having a top-gate structure, including with a traditional TFT with a top-gate structure, can skip the use of photomask at two occasions during the production process, thus lowers the production cost.
