A display panel and a display device are provided in the present disclosure. The display panel includes a base substrate; an array layer, on a side of the base substrate; a plurality of light-emitting units, on a side of the array layer away from the base substrate, where a light-emitting unit of the plurality of light-emitting units includes a first electrode, a light-emitting layer, and a second electrode which are sequentially disposed away from the base substrate; a pixel defining layer, on the side of the array layer away from the base substrate, where the pixel defining layer includes a plurality of pixel openings, the plurality of pixel openings correspond to the plurality of light-emitting units, and a projection of the light-emitting layer on the pixel defining layer is within a pixel opening; and a first metal part between the array layer and the first electrode.
