Abstract
A display panel and a display device are provided. The display panel includes a display region, a hole-digging region, and a boundary region disposed between the display region and the hole-digging region. The display panel also includes an array substrate and a light-emitting function layer. The array substrate includes a dam structure disposed between the display region and the boundary region. The light-emitting function layer covers the array substrate, and includes a first light-emitting component disposed over the display region and a second light-emitting component disposed over the boundary region. The array substrate further includes a base substrate and a driving device layer, and the driving device layer includes a first thin-film transistor device layer and a boundary driving circuit layer. The first thin-film transistor device layer is electrically connected to the first light-emitting component, and the boundary driving circuit layer is electrically connected to the second light-emitting component.
