The embodiment of the invention provides a display panel and a display device. The display panel comprises a first substrate and a second substrate which are arranged in a box-to-box mode. The first substrate comprises a display area and a peripheral area, the peripheral area comprises a first area, a second area and a third area which are sequentially connected in the direction away from the display area, a gate drive control line is arranged in the first area, a common voltage signal line connected with the display area is arranged in the third area, and the second area is located between the first area and the third area; the second substrate is provided with a black matrix, and the black matrix does not completely cover the first area, the second area and the third area. According to the design, the coverage area of the black matrix is reduced, the coupling capacitance of the gate drive control line, the common voltage signal line and the black matrix is reduced, and even the coupling capacitance does not
