Abstract
A display device includes: a substrate including a first region and a second region, an anode at the first region, an organic layer on the anode at the first region and on the second region, an electron injection layer on the organic layer at the first region and the second region, the electron injection layer including a first metal, a cathode on the electron injection layer at the first region, the cathode including a second metal having a greater work function than a work function of the first metal, and a capping layer on the cathode at the first region, and on the electron injection layer at the second region.
Claims20
A display device, comprising:
- a substrate comprising:
- a first region;
- and
- a second region;
- a thin-film transistor including an oxide semiconductor layer, the thin-film transistor disposed on the first region of the substrate;
- an inorganic protect film disposed on the substrate at the second region and the thin-film transistor at the first region;
- a planarization film over the thin-film transistor at the first region, the planarization film disposed on the inorganic protect film;
- an anode on the planarization film, the anode being disposed at the first region;
- a bank to cover an edge of the anode and the planarization film;
- an organic layer on the anode at the first region, and on the second region;
- a common layer on the organic layer at the first region and the second region;
- a cathode on the common layer at the first region;
- at least one capping layer including at least one organic capping layer on the cathode at the first region, and on the common layer at the second region;
- a plurality of inorganic encapsulation films and an organic encapsulation film disposed on the at least one capping layer;
- and
- a color filter layer provided on the plurality of inorganic encapsulation films and the organic encapsulation film at the first region corresponding to the anode,
- wherein the organic layer comprises a plurality of organic stacks each having a light emitting layer and at least one charge generation layer between adjacent organic stacks, and
- wherein the at least one charge generation layer is disposed on the first region and extends to the second region.
