1. A pixel of a display device, the pixel comprising:
a second capacitor coupled between a first node and a second node;
a first transistor including a gate coupled to the second node;
a second transistor configured to transfer a data voltage to the first node in response to a writing signal;
a sixth transistor configured to couple the first transistor and a light emitting element in response to an emission signal;
a seventh transistor configured to apply an anode initialization voltage to an anode of the light emitting element in response to an anode initialization signal; and
the light emitting element including the anode and a cathode coupled to a line of a second power supply voltage,
wherein a frame period for the pixel includes a scan period and a first hold period,
wherein, in the scan period, the writing signal and the anode initialization signal are applied while the sixth transistor is turned off,
wherein, in the first hold period, the anode initialization signal is applied while the sixth transistor is turned off, and
wherein a number of the anode initialization signal applied to the seventh transistor in the first hold period is greater than a number of the anode initialization signal applied to the seventh transistor in the scan period.
