The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. The display panel and the display device can improve the sensitivity of apressure sensor. The display panel includes a display area, the pressure sensor and a surrounding area positioned at the periphery of the display area; the pressure sensor is positioned at the surrounding area and comprises a first pressure sensing resistor, a second pressure sensing resistor, a third pressure sensing resistor and a fourth pressure sensing resistor which are electrically connectedwith one another in an end-to-end mode in sequence. The pressure sensor also includes a first auxiliary resistor; when certain pressure stress is vertically performed on the surface of the display panel, the first auxiliary resistor is electrified with the first pressure sensing resistor, and the first pressure sensing resistor has a first resistance value on a branch circuit where the first pressure sensing resistor is located; when the pressure stress is not vertically performed on the surface of the display panel, the first pressure sensing resistor has a second resistance value on the branch circuit where the first pressure sensing resistor is located, and the first resistance value is smaller than the second resistance value.
