Abstract
An emitting device in an organic electroluminescent device is disclosed, in which a lower electrode pattern is formed on a substrate, an emitting layer pattern is formed on the lower electrode pattern, and a transparent electrode is formed on the emitting layer pattern and an emitting body having a structure in which an organic thin film emits light when an application current is applied to it. The pattern of the transparent electrode completely covers and is larger than that of the lower electrode. The pattern of the transparent electrode is formed over the entire area of the pattern of the lower electrode.
