There is provided a display device comprises a substrate comprising a display area in which emission areas; a circuit layer; and an element layer comprising light emitting elements disposed in the emission areas. The circuit layer comprises light emitting pixel drivers electrically connected to the light emitting elements and arranged in a plurality of pixel columns and a plurality of pixel rows; and a first power line transmitting a first power to the light emitting pixel drivers. The first power line comprises power auxiliary lines extending in one direction; and mesh auxiliary electrodes electrically connected to the power auxiliary lines. Among the power auxiliary lines, two power auxiliary lines neighboring each other are electrically connected to each other through mesh auxiliary electrodes disposed between the two power auxiliary lines and parallel to each other in the one direction, among the mesh auxiliary electrodes.
