1. A display device comprising:
a substrate;
a first bank structure and a second bank structure spaced from each other on the substrate;
a first electrode on the first bank structure and a second electrode on the second bank structure;
a light emitting element located between the first electrode and the second electrode; and
wherein the first bank structure comprises a base layer, an upper layer on the base layer, and an intermediate layer between the base layer and the upper layer,
wherein the first electrode covers the first bank structure,
wherein an emission area and a non-emission area are defined in the substrate,
wherein the first bank structure, the second bank structure, and the light emitting element are located in the emission area,
wherein the display device further comprises a first transistor in the non-emission area of the substrate and comprising a first active material layer, a first gate electrode on the first active material layer, and a source/drain electrode in contact with at least a partial area of the first active material layer, and
wherein the first gate electrode is at a same layer as the base layer of the first bank structure.
