Embodiments of the present application disclose a display panel and a display device. The display panel comprises a driving substrate, a plurality of light emitting elements, a first pixel defining structure and a second pixel defining structure. The plurality of light emitting elements are located on one side of the driving substrate. The first pixel defining structure is located on one side of the driving substrate, and the first pixel defining structure comprises a pixel opening part and a pixel defining part. The light emitting elements are located in the pixel opening part, and the pixel defining part surrounds at least part of the light emitting elements. The second pixel defining structure surrounds at least part of the light emitting elements, and a undercut structure is arranged on one side of the second pixel defining structure facing the light emitting elements. In this way, the position and opening size of the light emitting elements are defined by the first pixel defining structure, so as to achieve a better large-viewing-angle light emission effect, and the adjacent light emitting elements are blocked by the second pixel defining structure, so as to reduce the horizontal leakage.
