Title
(EN) ORGANIC ELECTROLUMINESCENCE DEVICE
(FR) DISPOSITIF ELECTROLUMINESCENT ORGANIQUE
Abstract
(EN)
An organic electroluminescence device comprising an organic compound layer including at least an organic light-emitting layer sandwiched by a pair of electrodes, i.e. an anode and a cathode, wherein the organic compound layer contains a light-emitting material and a bis-condensation aromatic cyclic compound. Crystallization is suppressed even after a long time driving or in a high temperature environment, and a practical organic EL device having enhanced durability is provided.
(FR)
La présente invention concerne un dispositif électroluminescent organique comprenant une couche de composé organique comprenant au moins une couche organique luminescente, prise en sandwich par une paire d'électrodes, c'est-à-dire une anode et une cathode, la couche de composé organique contenant une substance luminescente et un composé aromatique cyclique à bis-condensation. La cristallisation est supprimée même après un fonctionnement de longue durée ou dans un environnement à température élevée, et l'invention a pour objet un dispositif EL organique pratique ayant une longévité accrue.
