摘要：
An organic EL light emitting device includes a transparent substrate, a transparent electrode film formed on the substrate, a positive electrode contact portion in contact with a part of the transparent electrode film and electrically connected therewith, an insulating layer formed on the transparent electrode film such that the an insulating layer covers a portion excluding a light emitting part, an organic light emitting layer formed on the transparent electrode film and on the insulating layer, a negative electrode film formed on the organic light emitting layer, a negative electrode contact portion in contact with at least a part of the negative electrode film and electrically connected therewith, and a protective layer for separating and electrically insulating the positive electrode contact portion and the transparent electrode film from the negative electrode contact portion.
