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.

Abstract: A gate driver includes stages connected to clock signal lines to which clock signals are applied and a first gate power line to which a first gate power voltage is applied, and outputting the first gate power voltage as gate signals in response to the clock signals. The clock signals have a first frequency and the first gate power voltage has a first voltage level in a first period. The clock signals have a second frequency lower than the first frequency and the first gate power voltage has a second voltage level in a second period. One of the first and second voltage levels is a gate-on voltage level that turns on a transistor, and another of the first and second voltage levels is a gate-off voltage level that turns off the transistor.
