Claim 0:
1. A display device comprising:
a display panel including a pixel including a switching element of a first type and a switching element of a second type that is different from the first type;
a gate driver which generates a gate signal based on a gate clock signal and provides the gate signal to the display panel;
a data driver which provides a data voltage to the display panel;
an emission controller which provides an emission control signal to the display panel; and
a driving controller which generates control signals for controlling the gate driver, the data driver, and the emission controller,
wherein, in a low-frequency driving mode, the driving controller is configured to provide the gate clock signal that swings between a high level and a low level at least three times to the gate driver during a writing frame for writing data to the pixel and to provide the gate clock signal having a direct current (DC) voltage to the gate driver during a holding frame for holding the data written in the pixel,
wherein during the writing frame, the emission control signal reaches a high level and a low level once each, and during the holding frame, the emission control signal reaches the high level and the low level at least once, respectively,
wherein the gate clock signal includes a first gate clock signal and a second gate clock signal,
during the holding frame, the first gate clock signal maintains the low level and the second gate clock signal maintains the high level.
