Abstract: A set circuit in a unit circuit in a gate driver of a display device includes a setting transistor, a first auxiliary transistor, and a second auxiliary transistor. The setting transistor includes a source terminal connected to an internal node, a gate terminal connected to a set input terminal, and a drain terminal connected to the set input terminal via the first auxiliary transistor and also connected to an input terminal via the second auxiliary transistor in a diode-connected form. Each transistor is controlled to be in an on state and an off state during normal drive and is controlled to be in the off state and the on state during a pause period by a control signal supplied to the input terminal.
