ABSTRACT:
There is provided an organic light-emitting device obtained by using a specific copper coordination compound as a light-emitting material, which has a basic structure in which two copper ions are crosslinked in a ring form by one of atomic groups containing a halogen atom, a sulfur atom, and an nitrogen atom. The light-emitting device provides high luminescence efficiency and high stability at low cost by using an inexpensive copper coordination compound as a light-emitting material.
