Abstract
A display device includes: a pixel unit including pixels connected to first scan lines, second scan lines, and data lines; a scan driver for supplying a first scan signal to the pixels through the first scan lines at a first frequency and supplying a second scan signal to the pixels through the second scan lines at a second frequency different from the first frequency in a first mode; a first signal supply for supplying an inspection signal to the pixels through at least one of the data lines in response to the first scan signal in a first period of the first mode; and a second signal for supply supplying a bias signal to the pixels through the data lines in response to the first scan signal in a second period of the first mode.
