Abstract: An array substrate and a display apparatus including the array substrate are provided. The array substrate includes a substrate divided into a display area and a peripheral area adjacent to the display area. A pixel array is formed on the substrate corresponding to the display area and receives a driving signal. A driving circuit includes a plurality of stages and is formed on the substrate corresponding to the peripheral area. Each of the stages includes a first transistor having a source electrode connected to an output terminal to output the driving signal, a channel layer formed between a gate insulating layer and the source electrode, the channel layer having an opening to facilitate contact between a portion of the gate insulating layer and the source electrode, and a capacitor defined by a gate electrode of the first transistor, the source electrode, and the gate insulating layer contacting the source electrode.
