Abstract: A display panel includes a pixel electrode, a common electrode which faces the pixel electrode, an auxiliary electrode spaced apart from the pixel electrode and connected to the common electrode, and a first functional layer between the pixel electrode and the common electrode, the first functional layer extending from the pixel electrode to the auxiliary electrode. The common electrode which is connected to the auxiliary electrode includes in order in a direction away from the first functional layer, a first layer including a transparent conductive material and having a thickness of about 500 angstroms to about 6000 angstroms, and a second layer including a conductive material and having a thickness of about 10 angstroms to about 100 angstroms.

Abstract: A display panel includes a pixel definition layer having a plurality of emission openings, a partition wall having a plurality of partition openings and having conductivity, a first emission element in a first emission opening and including a first light emitting material, and a second emission element in a second emission opening and including a second light emitting material. A contact area between the first emission layer and the partition wall and a contact area between the second emission layer and the partition wall are different from each other.
