PROBLEM TO BE SOLVED: To provide an organic light emitting element presenting an extremely high purity luminescent color phase and having an optical output of high efficiency and high luminance with a long life. SOLUTION: In an organic light emitting element constituted of a positive electrode and a negative electrode and one or a plurality of layers of organic compound layers interposed between a pair of the electrodes, at least one layer out of the organic compound layers contains at least one kind of a bis-acetylene compound as expressed by a general formula [1]. Provided that, in the general formula [1], Y and Z express substituted or unsubstituted aryl groups, heterocyclic groups, fused polynuclear aromatic groups, fused polynuclear heterocyclic groups, alkyl groups, aralkyl groups, alkoxy groups or the like, and substituted amino groups, or cyano groups, and may be the same or different. X expresses a substituted or unsubstituted arylene group, alkylene group, cycloalkylene group, heterocyclic group of bivalence, a fused polynuclear aromatic group, or a fused polynuclear heterocyclic group.
