A method of fabricating a display device includes forming a circuit layer on a base layer, forming a first preliminary electrode and a second preliminary electrode on the circuit layer, forming a photoresist layer on the first preliminary electrode and the second preliminary electrode, patterning the photoresist layer to form a photoresist pattern, treating a region of each of the first preliminary electrode and the second preliminary electrode to form a first electrode and a second electrode having regions of lower and higher electrical resistance, and disposing a light-emitting element on the first electrode and the second electrode at regions having lower electrical resistance.
