PURPOSE: To provide a light-emitting element having higher light-emitting efficiency. CONSTITUTION: The phosphorescence emitting compound, having a planar molecule skeleton is mixed in the liquid crystal compound having a discotic phase or a smectic phase to form a light-emitting layer, and this light-emitting layer is pinched by a pair of electrodes so as to form a light-emitting element.
