1. A display device comprising:
a substrate;
pixels disposed on the substrate, each of the pixels comprising:
a first electrode;
a second electrode; and
a plurality of light emitting elements electrically connected between the first and the second electrodes; and
a first oscillator disposed on the substrate and electrically connected to a first electrode of a first pixel of the pixels, the first oscillator converting a direct current (DC) voltage to an alternating current (AC) voltage, supplying the alternating current (AC) voltage to the first electrode of the first pixel of the pixels to align the plurality of light emitting elements between the first and second electrodes, and comprising:
at least one transistor; and
at least one capacitor.
