1. An OLED display panel, comprising a display area and an overlapping area, and further comprising:
a substrate;
a driving circuit layer disposed on a side of the substrate and comprising a terminal;
a light-emitting functional layer disposed on a side of the driving circuit layer away from the substrate, and comprising an electron transport layer and an electron injection layer, wherein the electron transport layer is disposed between the driving circuit layer and the electron injection layer;
a cathode layer disposed on a side of the electron injection layer away from the electron transport layer; and
a conductive layer disposed in the overlapping area and comprising a first conductive layer and a second conductive layer, wherein the first conductive layer is disposed between the terminal and the second conductive layer and comprises a plurality of protrusions, the second conductive layer is disposed between the first conductive layer and the electron transport layer, the electron injection layer is disposed between the electron transport layer and the cathode layer, 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.
