Original Abstract Submitted
a display device includes a substrate; an auxiliary electrode including metal layers stacked in an undercut structure; and a light-emitting element layer. the light-emitting element layer includes a second common layer; and a common electrode which extend to the non-emission area. a side surface of the auxiliary electrode includes a first bonding portion in contact with the second common layer, and a second bonding portion in contact with the common electrode. the auxiliary electrode includes a first side and a second side facing each other in one direction, and a third side and a fourth side facing each other in other direction crossing the one direction. the first bonding portion has a first width at a first point of the first side and has a second width smaller than the first width at a second point of the third side.
