Display device having mux part and method of driving the same

A display device comprising:

• a display panel including a data line, a power line, and a pixel circuit, the pixel circuit comprising:
• a driving transistor that is electrically connected to the power line, the driving transistor configured to control a driving current;
• a switching transistor connected to the data line and the driving transistor, the switching transistor configured to supply a data voltage supplied by the data line to the driving transistor;
• and a light emitting element that is electrically connected to the driving transistor, the light emitting element configured to emit light according to the driving current;
• and a circuit configured to output a mux signal having a first voltage to the driving transistor via the power line at a second time and output the mux signal having a second voltage that is less than the first voltage at a first time that is before the second time, the second voltage of the mux signal at the second time based on the data voltage, wherein the second voltage of the mux signal is a sum of the data voltage and an offset voltage.
