The substrate includes a display area and a pad area. The TFT structure is disposed on the substrate in the display area. The bonding line is disposed on the substrate in the pad area. The bonding pad is disposed on a side of the bonding line away from the substrate. The bonding pad includes a thin film for blocking moisture and oxygen. The luminescent functional layer is disposed on a side of the TFT structure away from the substrate. The thin film for blocking moisture and oxygen is disposed on the bonding line, thereby blocking moisture and oxygen from corroding the bonding line.

Abstract: A display panel, a manufacturing method thereof, and a display device are provided. The display panel includes a substrate and a light emitting device layer disposed on the substrate, and the light emitting device layer includes a first electrode layer, a light emitting layer, and a second electrode layer disposed on the substrate in a stacked manner. The present application provides a first auxiliary electrode disposed between the substrate and the light emitting layer, where, the first auxiliary electrode includes a first undercut opening penetrating through the first auxiliary electrode, where a side edge of the first auxiliary electrode is exposed within the opening, the light emitting layer is disconnected at first undercut opening, the second electrode layer is disposed continuously at the first undercut opening, and at least a portion of the second electrode layer is in contact with the edge of the first auxiliary electrode.

Abstract: Provided is a display panel comprising an anode layer, a sacrificial layer disposed on an anode layer, a pixel definition layer covering the sacrificial layer and the anode layer, and a light-emitting functional layer disposed in the groove and the light-emitting area opening, and a manufacturing method thereof, wherein the sacrificial layer is formed with a groove at a position corresponding to the light-emitting area opening. In this way, the sacrificial layer forming at the light-emitting area opening can be removed to form a groove at the same time in the process of forming the light-emitting area opening by exposure and development, so that it is possible to ensure that no pixel definition layer remains on the anode layer at the light-emitting area opening, thereby solving the problem that the light-emitting functional layer cannot be spread.

Abstract: A display panel and a method of manufacturing the display panel are provided in the present application. An auxiliary cathode is disposed in the driving circuit layer of the display panel, at the same time, a strapping hole is disposed on the auxiliary cathode. The cathode layer can extend into the strapping hole and contact with a conductive structure. Therefore, a voltage drop can be improved.
