Abstract: The present application discloses a display panel and a display device. The display panel includes a plurality of multiplexing drive modules, a plurality of drive branches and M drive buses. By electrically connecting one drive bus to N drive branches, the number of used drive buses can be reduced, thereby reducing the number of output channels of a drive signal source. Sine the number of used drive buses is reduced, the multiplexing drive modules can complete transmission of a frame of data signals using a less number of times of time-divisional parts for switching on transistors.
