1. A pixel comprising:
a light-emitting element;
a driving switching element which applies a driving current to the light-emitting element; and
a noise switching element which outputs a noise signal to an input electrode of the driving switching element in response to a noise control signal having a noise frequency and applied to a control terminal of the noise switching element,
wherein the noise frequency is equal to or only greater than a driving frequency of the pixel, and
wherein as the driving frequency decreases, the noise frequency decreases.
