OG exemplary drawing
 
1. A pixel of a display device, the pixel comprising:
a light emitting element including an anode; and
a transistor configured to apply an anode initialization voltage to the anode of the light emitting element in response to an anode initialization signal,
wherein a period in which the pixel is driven at a first driving frequency includes a first scan period, and a second scan period subsequent to the first scan period,
wherein a period in which the pixel is driven at a second driving frequency lower than the first driving frequency includes a third scan period, and a first hold period subsequent to the third scan period,
wherein the first scan period, the second scan period, the third scan period and the first hold period have a same time length, and
wherein an on-period of the anode initialization signal in the first hold period is longer than an on-period of the anode initialization signal in the third scan period.
