Abstract

The present invention addresses the problem of providing a novel aromatic heterocyclic derivative, providing an organic EL element that uses the derivative and has high luminous efficiency, long luminescence life, and few changes over time when used under high temperatures, and providing a display device and an illumination device that are equipped with the organic El element. This aromatic heterocyclic derivative is characterized by having a specific structure which includes a carbazole ring.

Description

technical field [0001] The present invention relates to an aromatic heterocyclic derivative, an organic electroluminescence element, an illuminating device and a display device using the same. More specifically, it relates to an aromatic heterocyclic derivative, an organic electroluminescent element using the same which has high luminous efficiency, long luminous lifetime, and little change over time even when used at high temperature, an illuminating device having the same, and display device. Background technique [0002] An organic electroluminescence element (hereinafter also referred to as an "organic EL element") is a thin-film type all-solid-state element in which an organic thin film layer (single-layer part or multi-layer part) containing an organic light-emitting substance is formed between an anode and a cathode. When a voltage is applied to this organic EL element, electrons are injected from the cathode to the organic thin film layer, and holes are injected fro...
