The invention discloses a display panel and a display device, and relates to the technical field of display. A display area of the display panel is provided with an arc boundary; the display panel includes a plurality of gate lines and a plurality of data signal lines, in the display area, the gate lines extend in a first direction and are distributed in a second direction, and all the data signallines are distributed in the first direction and extend in the second direction; a non-display area is provided with a plurality of gate driving circuits, and each gate driving circuit comprises a plurality of cascaded shift registers electrically connected with the corresponding gate lines respectively; the non-display area is further provided with a first circuit placement area located at the side, away from the display area, of the arc boundary; in the non-display area at the arc boundary, the gate lines led out from the shift registers wind from one side of the first circuit placement area to the display area; in the non-display area at the arc boundary, the data signal lines are located between the first circuit placement area and the display area. According to the scheme, the improvement of the display effect of the display panel and the display device is facilitated.
