Abstract: A display device can include a display panel having an display area and a dummy area surrounding the display area, a plurality of sub-pixels disposed in the display area, a plurality of dummy sub-pixels disposed in the dummy area, a pixel circuit disposed in the plurality of sub-pixels, and at least a pair of low potential power supply lines disposed in each of the plurality of sub-pixels and the plurality of dummy sub-pixels. Therefore, it is possible to reduce or minimize transfer issues of light emitting elements in an outer portion of the display area by forming the low potential power supply lines for self-assembling the light emitting element in the dummy area.
