Abstract
A display device may include pixels coupled to scan lines and data lines, at least one scan driver for supplying a scan signal to the pixels through the scan lines, and a data driver for supplying a data signal and a bias signal to the pixels through the data lines. The pixels are supplied with the data signal when the scan signal is supplied during display periods, and are supplied with the bias signal when the scan signal is supplied during a bias period between the display periods. By the bias signal, a bias voltage is supplied to first group pixels that emit light with a preset grayscale during the display periods.
