Abstract
A top emission organic EL device includes a substrate; a reflective layer formed on the substrate; a transparent first electrode formed on the reflective layer; a functional layer containing an organic light-emitting layer and formed on the transparent first electrode; a transparent second electrode formed on the functional layer; an optical length adjustment layer formed on the transparent second electrode; and a transflective layer formed on the optical length adjustment layer. In the organic EL device, an optical resonator is formed between the reflective layer and the transflective layer.
