Abstract
An active matrix organic light-emitting diode display panel is provided and includes a first metal layer, an interlayer dielectric layer, a second metal layer, a planarization layer and a transparent conductive layer sequentially located on a substrate. Second via holes are defined in the planarization layer. The transparent conductive layer is connected to the second metal layer through the second via holes. A contact surface of the second metal layer and the transparent conductive layer is a waved surface.
