Abstract
The present disclosure provides an organic light emitting diode (OLED) display panel and a display device. The OLED display panel includes a substrate, a driving circuit layer, a planarization layer, a luminescent functional layer, an encapsulation layer, and a touch layer including touch electrodes. The luminescent functional layer includes a pixel electrode layer, a pixel definition layer, a luminescent material layer, and a common electrode layer. The pixel definition layer is patterned to form pixel definition regions and grooves. Projections of the touch electrodes on the substrate and projections of the grooves on the substrate are at least partially overlapped, thereby improving a touch report rate of the OLED display panel.
