Abstract: A display apparatus includes a display panel, a data driver and a gate driving circuit. The display panel includes pixels, data lines, and gate lines. The data driver applies data voltages to the data lines. The data driver includes dummy stages. The gate driving circuit applies gate signals to the gate lines, and is disposed between opening portions in a display area of the display panel. The gate driving circuit includes normal stages that output the gate signals to the gate lines. The dummy stages output a reset signal to at least one of the normal stages.

Abstract: Each stage of a gate driver includes a controlling part which increases an electric potential of a boosting line in response to a carry signal of a previous stage and decreases the electric potential of the boosting line in response to the carry signal of a next stage, a first output part which turns on in response to the increased electric potential of the boosting line and receiving a clock signal to output a gate signal of a present stage, and a second output part which turns on in response to the increased electric potential of the boosting line and receiving the clock signal to output the carry signal of the present stage. The boosting line of the present stage is disposed adjacent to a gate line which is connected to one of next stages following the present stage.
