Abstract
The present invention is related to an imidazole ring-containing compound and an organic electroluminescence (EL) display device using the same. In particular, the imidazole ring-containing compound may be used alone or in combination with a dopant as a material for organic films such as an electroluminescent layer. The organic EL display device using an organic film made of the imidazole ring-containing compound has improved characteristics such as luminance, efficiency, driving voltage, and color purity.
