Provided are a display panel and a display device. The display panel includes a gate drive circuit, a plurality of impedance regulation circuits and a control module. The gate drive circuit includes a plurality of cascaded first shift registers. The plurality of cascaded first shift registers are electrically connected to a plurality of scanning lines in one to one correspondence; and the plurality of impedance regulation circuits are in one-to-one correspondence with the plurality of scanning lines. Each of the plurality of impedance regulation circuits is in series connection between a first shift register corresponding to the each of the plurality of impedance regulation circuits and a scanning line corresponding to the each of the plurality of impedance regulation circuits. The each of the plurality of impedance regulation circuits includes at least one transistor.
