1. A pixel of a display device, the pixel comprising:
a storage capacitor electrically connected between a first node and a second node;
a first switching transistor configured to electrically connect a data line to the first node in response to a scan signal;
a driving transistor including a gate electrically connected to the first node, a first terminal, and a second terminal electrically connected to the second node;
a second switching transistor configured to electrically connect an initialization line to the second node in response to an initialization signal; and
a light emitting element electrically connected to the second node,
wherein the first node has a first initialization voltage in a first period of a first horizontal time and has a second initialization voltage unequal to the first initialization voltage in a second period of the first horizontal time.
