Display device and method of driving the same

A method of driving a display device, the method comprising:

• providing data including a pre-emphasis value and an image data value;
• selectively supplying a first gamma reference voltage and a second gamma reference voltage different from the first gamma reference voltage;
• and
• supplying a pre-emphasis voltage, that is generated based on the pre-emphasis value and the first gamma reference voltage, to data lines during a first period of a horizontal period, and supplying a data voltage generated, that is based on the image data value and the second gamma reference voltage, to the data lines during a second period of the horizontal period,
• wherein, in the selectively supplying of the first gamma reference voltage and the second gamma reference voltage, the first gamma reference voltage is supplied during the first period, and the second gamma reference voltage is supplied during the second period.
