Abstract: An array substrate has a display area and a peripheral area located outside the display area. The display area includes two first sides that are substantially parallel and arc sides connected to ends of the first sides. The array substrate includes at least one gate driving circuit. Each gate driving circuit includes GOA units sequentially distributed along each arc side in at least one arc side and active GOA units sequentially distributed along a first side connected to the arc side. The GOA units includes at least one active GOA unit and at least one dummy GOA unit. Each active GOA unit is configured to provide a driving signal to at least one sub-pixel. A distance between two adjacent GOA units in the GOA units is approximately same as a distance between two adjacent active GOA units in the active GOA units.
