Abstract
An organic electroluminescent device includes at least two light-emissive units provided between a cathode electrode and an anode electrode opposed to the cathode electrode, each of the light-emissive units including at least one light-emissive layer. The light-emissive units are partitioned from each other by at least one charge generation layer, the charge generation layer being an electrically insulating layer having a resistivity of not less than 1.0×102 Ωcm.
Claims20
An organic electroluminescent device-comprising a plurality of light-emissive units on a substrate, the plurality of light-emissive units provided between a cathode electrode and an anode electrode opposed to said cathode electrode, said plurality of light-emissive units comprising at least one light-emissive layer,
- wherein respective neighboring units of each of said light-emissive units is partitioned from each other by a charge generation layer
- wherein said charge generation layer comprises an electron accepting material and an electron donating material;
- and
- wherein each said light emissive layer in each said light-emissive unit is arranged to only emit light in an intersecting area between said cathode electrode and said anode electrode.
