Abstract
The present disclosure provides a display panel and a display device, including a display area and a non-display area. The non-display area includes a circuit area and a fan-out wiring area arranged side by side with the display area along a first direction in sequence. The fan-out wiring area includes a plurality of first fan-out wirings with lengths gradually decreasing along a second direction perpendicular to the first direction. The circuit area includes a plurality of first sub-circuit areas in a one-to-one correspondence with the plurality of first fan-out wirings. Widths of the plurality of the first sub-circuit areas in the first direction gradually decrease along the second direction.
