The invention provides a multiplexing circuit and a display device. The multiplexing circuit comprises a control signal output module and a multiplexing module electrically connected with the controlsignal output module. The control signal output module comprises a first wire, a second wire, a resistor and a capacitor; the first end of the first wire receives a control signal, and the second endis electrically connected with the first end of the resistor. The first end of the second wire is electrically connected with the second end of the resistor, and the second end of the second wire is electrically connected with the multiplexing module; the first end of the capacitor is electrically connected with the second end of the resistor, the second end is grounded, the resistance distribution on the signal transmission path is destroyed and controlled by additionally arranging the resistor, the peak current of the circuit can be reduced, and the stability of the circuit is improved.
