摘要： A display panel and an electronic device are provided. In the display panel, by disposing an auxiliary electrode in a first opening of a pixel definition layer, a first electrode is electrically connected to an auxiliary electrode line through the auxiliary electrode, so as to reduce a resistance of the first electrode. Therefore, uneven display due to voltage drop is remedied, so that a problem of large cathode resistance existing in a current display panel is relieved. Meanwhile, the first opening of the pixel definition layer of the present application exposes a part of a lateral wall of the auxiliary electrode. An organic light-emitting layer is cut off at a position of the first opening exposing the at least part of the lateral wall. The first electrode is electrically connected to the at least part of the lateral wall exposed by the organic light-emitting layer.
