Provided are organometallic complexes that can exhibit phosphorescence. One of the novel organometallic complexes is represented by General Formula (G1). In General Formula (G1), R1 represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aralkyl group having 7 to 10 carbon atoms which may have a substituent. In addition, R2 represents any of an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms which may have a substituent, and an aryl group having 6 to 12 carbon atoms which may have a substituent. Further, Ar represents an arylene group having 6 to 13 carbon atoms which may have a substituent. Further, M represents a Group 9 element or a Group 10 element.
The facile and scalable method enabled synthesis of CzDABNAs, exhibiting narrowband thermallyactivateddelayedfluorescence with emission spectra ranging from deepblue to green. The organiclight‐emittingdiode devices employing these products as emitters exhibited deep‐blue, sky‐blue, and green emission with high external quantum efficiencies of 19.5, 21.8, and 26.7 %, respectively.

Disclosed is an organic light-emitting display device that comprises a light-emitting layer formable simply by a wet process and has a prolonged service life. Also disclosed is an organic light-emitting device that comprises an upper transparent electrode having a lowered wiring resistance that can lower wiring resistance-derived power consumption. Further disclosed are a method and an apparatus for manufacturing an organic light-emitting element having a prolonged service life. In a first embodiment, an organic light-emitting display device is provided that comprises a moisture capturing layer provided between an upper electrode and a lower electrode. In a second embodiment, an organic light-emitting apparatus is provided that comprises a metal substrate, an organic light-emitting element provided on the metal substrate, and an upper transparent electrode connected electrically to the metal substrate through a contact hole. In a third embodiment, a method for manufacturing an organic light-emitting element comprising a first organic compound including a light-emitting layer and a second organic compound is provided that comprises the steps of forming the first organic compound, heating the first organic compound in vacuo, and forming the second organic compound.
Disclosed is an organic light-emitting display device comprising a transparent lower electrode and a reflective upper electrode. Between said electrodes there is a light emitting layer and a moisture capturing layer.
The light-emitting layer is formed by a wet process. The moisture capturing layer suppresses moisture-caused deterioration, thereby prolonging the service life of the display device. The upper transparent electrode lowers the wiring resistance thereby reducing power consumption of a display device using it.
