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.

Abstract: A display apparatus includes a first substrate, a second substrate, and a driver chip. The first substrate includes a plurality of gate lines disposed in the display area and extended in a first direction, a plurality of data lines disposed on a gate insulating layer insulating the gate lines and extended in a second direction substantially perpendicular to the first direction, and a gate driving circuit section disposed in the first peripheral area adjacent to first ends of the gate lines. The second substrate is opposite to the first substrate. A liquid crystal is interposed between the first and second substrates. The driver chip is disposed in the second peripheral area adjacent to second ends of the gate lines opposite to the first ends so that the width of the upper and lower portions of the display area may be decreased.
