A display device includes a first substrate including a display area and a non-display area, first banks spaced apart from each other in the display area and in the non-display area on the first substrate, electrodes spaced apart from each other on the first banks in the display area, dummy electrodes spaced apart from each other on the first banks in the non-display area, a first pattern between the electrodes in the display area, a second pattern between the dummy electrodes in the non-display area, a first light emitting element on the first pattern, a second light emitting element on the second pattern, contact electrodes respectively on the electrodes in the display area to contact one end of the first light emitting element, and dummy contact electrodes respectively on the dummy electrodes in the non-display area to contact one end of the second light emitting element.
