Estimating the term…
The present invention provides an organic light emitting device including an organic layer of two or more organic layers including a first electrode, a second electrode and an emission layer disposed between the two electrodes, wherein the organic layer includes a first injection or transport layer including a material having a LUMO energy level of −4 eV or lower and a second hole injection or transport layer including a material having a HOMO energy level of −4 eV or lower and a material having a LUMO energy level of −4 eV or lower, which is in contact with the first hole injection or transport layer and a method for manufacturing the organic light emitting device.
An organic light emitting device comprising a first electrode, a second electrode and two or more organic layers including an emission layer disposed between the two electrodes, wherein the organic layers comprises a first hole injection or transport layer including a material having a LUMO energy level of −4 eV or lower and a second hole injection or transport layer including a material having a HOMO energy level of −4 eV or lower and a material having a LUMO energy level of −4 eV or lower, which is in contact with the first hole injection or transport layer.
A stacked organic light emitting device comprising a first electrode, a second electrode and at least two light emitting units disposed between the two electrodes, wherein the light emitting unit includes an emission layer, a first injection or transport layer including a material having a LUMO energy level of −4 eV or lower and a second hole injection or transport layer including a material having a HOMO energy level of −4 eV or lower and a material having a LUMO energy level of −4 eV or lower, which is in contact with the first hole injection or transport layer.
