Abstract
A display apparatus includes a display panel, a data driving circuit and a gate driving circuit. The display panel displays an image and includes a plurality of pixels. The data driving circuit applies a data voltage to a data line of the display panel. The gate driving circuit applies a gate output signal to a gate line of the display panel. The gate driving circuit is disposed between opening portions in a display area of the display panel. The gate driving circuit includes a normal stage column extending in a pixel column direction of the display panel and including a plurality of normal stages and a dummy stage column disposed adjacent to an end portion of the normal stage column in a pixel row direction and including a plurality of dummy stages.
