Metal complex, light-emitting device, and display apparatus
A metal complex is provided which is used for an organic EL device and an organic light-emitting device which outputs light with high luminance and high efficiency. The metal complex has a structure in which a nitrogen atom in a 6- to 8-membered non-aromatic cyclic group is bonded to a metal atom. The organic light-emitting device includes a pair of electrodes which are an anode and a cathode, and an organic compound layer interposed between the electrodes. The organic compound layer contains the metal complex represented by the following structural formula.
1. A metal complex represented by any one of the following formulas:
2. An organic light-emitting device comprising:
a pair of electrodes; and
an organic compound layer interposed between the electrodes,
wherein the organic compound layer includes the metal complex according to claim 1 .
3. An organic light-emitting device according to claim 2 , wherein the organic compound layer is a light-emitting layer.
4. A display apparatus comprising the organic light-emitting device according to claim 3 .
