摘要： 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.

摘要： An embodiment of the present invention discloses a display panel and a manufacturing method thereof. The display panel includes a driver wiring layer, an electron transport layer, an electron injection layer, and a cathode layer. The driver wiring layer includes a cathode voltage line, and the electron transport layer is connected to the cathode voltage line. The cathode layer is connected to the electron injection layer. Patterns of the electron transport layer and the electron injection layer are the same as a pattern of the cathode layer. The display panel further includes a resistance reduction layer located between the cathode voltage line and the electron transport layer. The present invention simultaneously patterns the cathode layer, the electron injection layer, and the electron transport layer by a mask plate and forms the same patterns.
