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.
