To provide a polarized light-emitting element with high brightness and a high degree of polarization capable of being easily manufactured and physical changes such as dimensional changes are unlikely to occur.SOLUTION: The polarized light-emitting element that emits polarized light is a polycyclic heterocyclic aromatic compound in which a luminescent compound or a salt thereof includes a nitrogen atom or a sulfur atom, which is formed as a film with the luminescent compound or its salt oriented. Lyotropic liquid crystallinity is exhibited in a state that a luminescent compound or a salt thereof is dissolved in a solvent, or in the process of drying the solvent.SELECTED DRAWING: None 【課題】高輝度かつ高偏光度の偏光発光素子を簡易に製造でき、かつ寸法変化などの物理的変化が起こりにくい偏光発光素子を提供する。【解決手段】発光性化合物又はその塩が窒素原子もしくは硫黄原子を含む多環複素環芳香族化合物であり、発光性化合物またはその塩が配向した状態で膜として形成する偏光を発光する偏光発光素子。発光性化合物またはその塩が溶媒に溶解した状態、もしくは溶媒が乾燥する過程でリオトロピック液晶性を示す。【選択図】なし
