Patent ID: 7314769

Claim:
A method for manufacturing a light emitting device comprising the step of: forming a light emitting layer by applying an organic material and a guest material comprising an organometallic complex by an ink jet method, wherein the organic material comprises dendrimer, and wherein the organometallic complex is represented by general formula (1), wherein each of R 1 to R 5 is selected from the group consisting of a hydrogen atom, a halogen atom, a lower alkyl group, an alkoxy group, an acyl group, a nitro group, a cyano group, an amino group, a dialkylamino group, a diarylamino group, a vinyl group, an aryl group, and a heterocyclic group, wherein Y is a heterocyclic group containing a nitrogen atom as a hetero atom, wherein M is at least one of atoms of group 9 and 10 in the periodic table, wherein when the M is the atom of group 9 in the periodic table, n=2, wherein when the M is the atom of group 10 in the periodic table, n−1, and wherein L is selected from the group consisting of a monoanionic bidentate chelate ligand having a beta diketone structure, a monoanionic bidentate chelate ligand having a carboxyl group and a monoanionic bidentate chelate ligand having a phenol hydroxyl group.
