Abstract: A display device includes a display panel including pixels; a panel driver to supply a scan signal and a data signal to the pixels; and a power supply to generate a first supply voltage and a second supply voltage, and to change the first supply voltage and/or the second supply voltage to provide it to the pixels. The pixels emit light in response to the scan signal based on the data signal during an emission period where a voltage difference between the first supply voltage and the second supply voltage is larger than a first reference voltage. A first voltage difference between the first supply voltage and the second supply voltage at a start of the emission period is larger than an average voltage difference between the first supply voltage and the second supply voltage throughout the emission period.
