The embodiment of the invention relates to the technical field of display, and provides a pixel structure, a display panel and a display device for weakening jaggies at the periphery of a display area. The pixel structure comprises multiple circular pixels; the circular pixels include one center pixel and multiple peripheral pixels; the peripheral pixels form multiple first pixel groups; multipleperipheral pixels in each first pixel group are distributed on the same circumference with the center pixel as the circle center; in the direction away from the center pixel, the radii of the circumferences where the peripheral pixels in different first pixel groups are distributed are gradually increased. The pixel structure is used for displaying images.
