Abstract:
Provided is an organic light-emitting element having high light-emitting efficiency and a long element lifetime, the organic light-emitting element including an anode, a cathode, and an organic compound layer placed between the anode and the cathode, in which: the organic compound layer includes an emission layer; the emission layer includes a host and a guest; the host is an aromatic hydrocarbon compound; the guest is an iridium complex of a specific structure; and a content of the host is 50 wt % or more with reference to the total amount of the constituent materials for the emission layer.
