Beschreibung
Zusammenfassung:	The present disclosure relates to a host material and an organic electroluminescent device comprising the same. By using a specific combination of two or more host compounds according to the present disclosure, the organic electroluminescent device of the present disclosure has luminous efficiency at least equivalent to or higher than conventional devices and has lifespan better than conventional devices. La présente invention concerne un matériau hôte et un dispositif électroluminescent organique le contenant. Grâce à l'utilisation d'une combinaison spécifique de deux composés hôtes ou plus selon la présente invention, le dispositif électroluminescent organique de la présente invention présente une efficacité lumineuse au moins équivalente ou supérieure à celle de dispositifs classiques et présente une meilleure durée de vie que les dispositifs classiques.
