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 has strong blue luminescence and hole transporting characteristics and may be used as a blue luminescent material and as a host of phosphorescent and fluorescent dopants in various colors such as red, green, blue, and white. In addition, an organic EL display device may be manufactured using the imidazole ring-containing compound of the present invention, which has high-efficiency luminescence characteristics and consumes less power.
