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.
Claims31
An organic electroluminescent device comprising:
- at least two light-emissive units provided between a plurality of cathode electrodes arranged in a first direction and a plurality of anode electrodes arranged in a second direction which is vertical with said first direction and opposed to said cathode electrode, each of said light-emissive units including at least one light-emissive layer;
- wherein said light-emissive units are partitioned from each other by at least one charge generation layer, and
- wherein said charge generation layer constituting an electrically insulating layer having a resistivity of not less than 1.0×102 Ωcm so that said light-emissive units are configured to emit light only from a light emissive area located between crossed area of said cathode electrode and said anode electrode.
