The invention provides a display panel and a display device, a display surface comprises a substrate, a driving device layer and a light-emitting device layer, the light-emitting device layer comprises a pixel defining layer, a first electrode layer, an organic function layer and a second electrode layer, the pixel defining layer comprises spacing parts and openings corresponding to light-emitting units, the spacing parts are arranged around the openings in an extending mode, and the first electrode layer is arranged on the substrate. The area of the first cross section of each interval part is gradually reduced in the direction away from the driving device layer, the first cross section is a cross section perpendicular to the extending direction of the interval part, and the first cross section is in a geometric figure with a tip top, and the first electrode layer comprises first electrodes arranged on the light-emitting units; the organic functional layer covers the surfaces of the sides, opposite to the dr
