An OLED display panel comprises an overlapping area, and further includes a driving circuit layer, a light-emitting functional layer, a cathode layer, and a conductive layer. In the overlapping area, a terminal of the driving circuit layer, a first conductive layer and a second conductive layer of the conductive layer, an electron transport layer and an electron injection layer of the light-emitting functional layer, and the cathode layer are disposed sequentially from bottom to top. The first conductive layer includes a plurality of protrusions. Each of the electron transport layer and the electron injection layer is disconnected at the protrusions, and the cathode layer is in contact with the protrusions.
