Abstract
An organic electro-luminescence device includes a substrate, the first electrode layer, a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, an electron injecting layer and the second electrode layer. The first electrode layer is formed over the substrate. The hole injecting layer is formed over the first electrode layer. The hole transporting layer is formed over the hole injecting layer. The light emitting layer is formed over the hole transporting layer. The electron transporting layer is formed over the light emitting layer. The electron transporting layer includes carbazole derivative and n-type material. The electron injecting layer is formed over the electron transporting layer. The second electrode layer is formed over the electron injecting layer.
