Original Abstract Submitted

a display device includes: a pixel which emits light at a luminance corresponding to a data voltage applied thereto; and a data driver which supplies the data voltage to the pixel. the data driver includes: a first amplifier which outputs a first reference voltage; a first booster circuit including an input terminal connected to a first input terminal of the first amplifier, and an output terminal connected to a second input terminal of the first amplifier; a second amplifier which outputs a second reference voltage; a resistance string which receives the first and second reference voltages, and generate gamma voltages which are intermediate voltages between the first and second reference voltages; a digital-analog converter which outputs a gamma voltage corresponding to a gray scale of the pixel among the gamma voltages; and a source amplifier which outputs the gamma voltage as the data voltage.
