1. A display device comprising a sub-pixel, the sub-pixel comprising:
a first substrate;
a first electrode on the first substrate;
a second electrode on the first substrate and spaced from the first electrode;
a plurality of light-emitting elements, each of the plurality of light-emitting elements connected between the first electrode and the second electrode and having respective end portions on the first and second electrodes;
a first connecting electrode on the first electrode and connected to one end of a light-emitting element from among the plurality of light-emitting elements;
a second connecting electrode on the second electrode and connected to an other end of the light-emitting element, the first connecting electrode and the second connecting electrode being at different layers;
a first transistor comprising a first first transistor electrode and a first second transistor electrode, the first first transistor electrode being connected to the first electrode and the first second transistor electrode being grounded; and
a second transistor comprising a first end connected to the second electrode and a second end grounded,
wherein the first transistor is forward-biased to the first electrode, and the second transistor is reverse-biased to the second electrode.
