Display device and driving method thereof

A display device, comprising:

• a display panel including a plurality of pixels defined by allowing a plurality of gate lines and a plurality of data lines to intersect each other;
• a timing controller configured to generate a gate control signal, a data control signal, a multiplexer (MUX) clock signal, and image data;
• a gate driving circuit configured to sequentially provide gate signals to the plurality of gate lines based on the gate control signal;
• a data driving circuit configured to supply a data signal to the plurality of data lines based on the image data and the data control signal to drive the plurality of pixels;
• and
• a MUX circuit configured to receive the data signal and output the data signal in a time division manner to the plurality of data lines according to the MUX clock signal,
• wherein the timing controller includes a slew rate control unit that controls a slew rate of the MUX clock signal, in which the slew rate control unit includes:
• a rising slew rate control unit configured to control the slew rate in a rising section of the MUX clock signal, and
• a falling slew rate control unit configured to control the slew rate in a falling section of the MUX clock signal.
