Display panel and display device

The embodiment of the invention provides a display panel which is provided with a display area and a frame area, the frame area is arranged on the periphery of the display area in a surrounding mode, and the edge line of the display area is an arc line. The edge line of the frame area is an arc line; the edge line of the display area is matched with the edge line of the frame area in shape; the display panel comprises a peripheral circuit and a peripheral signal line, the peripheral circuit and the peripheral signal line are distributed in the frame area, and the peripheral circuit and the peripheral signal line are sequentially distributed away from the display area; the display panel further comprises an array substrate and a color film substrate, and the array substrate and the color film substrate are in box alignment. The array substrate and the color film substrate are not overlapped on the first side edge; in the frame area outside the frame area where the first side edge is located, the width range between the signal line closest to the outer side edge of the frame area in the peripheral signal lines and the outer side edge of the frame area is 0.35 +/-0.2 microns; the outer edge of the frame area is the edge of the side, away from the display area, of the frame area.
