(FR) DISPOSITIF ORGANIQUE ELECTROLUMINESCENT ET AFFICHAGE
(JA) 有機エレクトロルミネッセンス素子及び表示装置
Abstract:
(EN) An organic electroluminescent device and a display are disclosed which have high luminous efficiency and long life. This organic electroluminescent device is characterized by comprising composition layers between a pair of electrodes which composition layers include at least a phosphorescent light-emitting layer and at least one layer of which composition layers contains a compound represented by the following general formula (1): (wherein Z1 represents an aromatic heterocyclic ring which may have a substituent; Z2 represents an aromatic heterocyclic ring or an aromatic hydrocarbon ring which may have a substituent; Z3 represents a divalent linking group or just a bonding hand; and R101 represents a hydrogen atom or a substituent).
(FR) L'invention concerne un dispositif organique électroluminescent et un affichage à haute efficacité lumineuse et à longue durée de vie. Ce dispositif organique électroluminescent se caractérise en ce qu'il comprend des couches de composition entre une paire d'électrodes, lesdites couches de composition comprenant au moins une couche électroluminescente phosphorescente, une couche au moins desdites couches de composition contenant un composé représenté par la formule générale suivante (1) (dans laquelle Z1 représente un noyau hétérocyclique aromatique pouvant avoir un substituant; Z2 représente un noyau hétérocyclique aromatique ou un noyau d'hydrocarbure aromatique pouvant avoir un substituant; Z3 représente un groupe de liaison divalente ou juste un élément de liaison; et R101 représente un atome d'hydrogène ou un substituant).
