Abstract: A display device includes: a first pixel connected to a first data line and a first scan line; a second pixel connected to the first data line and a second scan line; a first scan driver connected to a first scan start line and the first scan line; and a second scan driver connected to a second scan start line and the second scan line. In a first frame period, the second scan start line is to be suppled with a second scan start signal having a turn-on level, after a first period elapses after a first scan start signal having a turn-on level is supplied to the first scan start line. In a second frame period, a difference between a time at which the first scan start signal having the turn-on level is supplied and a time at which the second scan start signal having the turn-on level is supplied corresponds to a second period. The second period is shorter than the first period.
