Abstract

A light-emitting element includes a first electrode, a functional layer disposed on the first electrode, a second electrode on the functional layer, and a capping layer on the second electrode. The second electrode includes a first layer on the functional layer, a second layer disposed on the first layer and including a different material from that of the first layer, and a third layer disposed on the second layer and including a different material from that of the second layer. The second layer includes sub-layers each including silver (Ag). The sub-layers include a first sub-layer on the first layer, a second sub-layer on the first sub-layer, and a third sub-layer on the second sub-layer. A film density of the first sub-layer and a film density of the second sub-layer are different, and the film density of the second sub-layer and a film density of the third sub-layer are different.
