1. A display device comprising:
a transistor on a substrate;
a via layer on the transistor;
a first electrode and a second electrode on the via layer and arranged in parallel to each other;
a first insulating layer on the first and second electrodes;
a first bridge pattern on the first insulating layer and connected to the transistor;
light-emitting elements having both end portions thereof on the first and second electrodes;
a first connecting electrode connected to first end portions of the light-emitting elements;
a second connecting electrode connected to second end portions of the light-emitting elements, and
a bank surrounding an emission area, in which the light-emitting elements are located, and surrounding a subarea, which is spaced in one direction from the emission area, with at least a portion of the bank being between the emission area and the subarea,
wherein the first connecting electrode is in contact with the first bridge pattern and is electrically connected to the transistor.
