Abstract: A display device includes a pixel connected to a first gate line, an emission control line, a bias gate line, and a data line. A gate driver is configured to supply a first gate signal to the first gate line in an address scan period and configured to supply a bias write gate signal to the bias gate line in a self-scan period. An emission driver is configured to supply an emission control signal in the address scan period and in a self-scan period. A data driver is configured to supply a first data voltage to the data line in the address scan period and configured to supply a second data voltage to the data line in the self-scan period. The second data voltage is set based on the first data voltage.
