摘要： 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.
