Abstract
An organic light emitting display is provided. The organic light emitting display comprises: a substrate; an anode that is positioned on the substrate; a sub-anode that is positioned on the anode and that is formed with a metallic oxide and nickel (Ni); an organic light emitting layer that is positioned on the sub-anode; and a cathode that is positioned on the organic light emitting layer.
Claims2
An organic light emitting display comprising:
- a substrate;
- an anode that is positioned on the substrate;
- a sub-anode that is positioned directly on the anode;
- an organic light emitting layer that is positioned directly on the sub-anode;
- and
- a cathode that is positioned directly on the organic light emitting layer,
- wherein the anode is formed with a metallic oxide selected from the group consisting of an indium tin oxide (ITO), an indium zinc oxide (IZO), and an indium tin zinc oxide (ITZO),
- wherein the sub-anode is formed with the metallic oxide and nickel (Ni) to supply a high work function, and
- wherein the sub-anode has a thickness smaller than that of the anode.
