Display panel and display device

The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. The display panel comprises a plurality of data lines, a plurality of connecting wires and a plurality of conductor modules. According to time-multiplexing of a display stage and a touch stage, the portion, stretching out of a display region of one data line and/or the corresponding connecting wire electrically connected with the data line are/is connected with at least one conductor module in series, and the sum of resistance values of the conductor modules connected with each data line and the corresponding connecting wire electrically connected with the data line in series is equal. According to the display panel and the display device, when the touch stage is ended, the touch panel is switched into the display stage; when data signals are started to be transmitted, due to the fact that the load resistance on a transmission line where the data lines and the corresponding connecting wires electrically connected with the data lines is large, the probability that large current is generated on the transmission line in the data signal transmission process is lowered, then, the probability that bright lines appear on the display panel is lowered, and the display effect of the display panel is improved.
