Abstract
A display device includes a first electrode and a second electrode which are disposed on a substrate and face each other. Light-emitting elements are disposed between the first electrode and the second electrode. Markings are formed on the first electrode in a first extending direction of the first electrode in a plan view.

A method of repairing a display device comprising:
- applying driving voltages to a first electrode and a second electrode extending to face each other on a substrate;
- forming markings on the first electrode or on an insulating layer adjacent to the first electrode;
- generating coordinate information of a defect based on a heating state of light-emitting elements disposed between the first electrode and the second electrode;
- generating the coordinate information based on the markings;
- and
- removing the defect from the display device based on the coordinate information.
