  • Publication number: 20240032384
    Abstract: A display panel and a method thereof for manufacturing the same are provided. The display panel includes a pixel electrode layer and an auxiliary electrode layer. A side surface of the pixel electrode layer away from an array substrate is lower than a side surface of the auxiliary electrode layer away from the array substrate, so that topography of a second opening is higher than that of a first opening of a light-emitting region of a pixel, and it is difficult for a light-emitting functional layer to be deposited into the second opening to decrease the resistance of a bridging portion between the second electrode layer and the auxiliary electrode layer.

  • Publication number: 20220384559
    Abstract: A display panel, a manufacturing method thereof, and a display device are provided. In the display panel, a first undercut structure and a second undercut structure are formed along a vertical direction of an overlappingly connecting hole of the first electrode layer and the auxiliary electrode layer. Therefore, an overlappingly connecting area between the first electrode layer and the auxiliary electrode layer can be enlarged. As such, the first electrode layer can be ensured to have high transparency and good conductivity, thereby solving an issue of IP drop of the first electrode. In addition, by using this undercut structure as well as using a metal line layer to overlappingly connect the first electrode layer with the auxiliary electrode layer, the overlappingly connecting area between the first electrode layer and the auxiliary electrode layer can be enlarged without reducing an aperture ratio of the display panel.
