1. A pixel comprising:
a first sub-emission area and a second sub-emission area;
a first light source unit disposed in the first sub-emission area, the first light source unit including at least one first light emitting element electrically connected between at least one first split electrode and a second power supply;
a second light source unit disposed in the second sub-emission area, the second light source unit including at least one second light emitting element electrically connected between at least one second split electrode separated from the at least one first split electrode and the second power supply;
a first driving circuit electrically connected between a first power supply and the at least one first split electrode, and supplying a first driving current to the first light source unit in response to a first data signal supplied to a first data line; and
a second driving circuit electrically connected between the first power supply and the at least one second split electrode, and supplying a second driving current to the second light source unit in response to a second data signal supplied to a second data line, wherein
a data driver generates the first data signal and the second data signal corresponding to frame data which is each pixel data in response to input image data, and
the second data signal includes a signal for blocking supply of a driving current to the second light source unit when the frame data includes a grayscale value less than a reference grayscale value.
