A display device and a method of driving the same are provided. The display device includes a control signal generator that generates a control signal, a first demultiplexer that time-divides a data voltage from a first channel of a data driver and distributes the data voltage from the first channel to two or more data lines, in response to the control signal, a signal delay part that delays the control signal, and a second demultiplexer that time-divides a data voltage from a second channel of the data driver and distributes the data voltage from the second channel to other two or more data lines, in response to the control signal delayed by the signal delay part.
