ORGANIC EL LIGHT EMITTING DEVICE, MANUFACTURING METHOD THEREFOR, AND ORGANIC EL ILLUMINATION DEVICE

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.

1. A manufacturing method of an organic EL light emitting device comprising:
forming a transparent electrode film on a transparent substrate; forming a positive electrode contact portion that is electrically connected to the transparent electrode film as a part of the transparent electrode film; forming a negative electrode contact portion on a part of upper side of the transparent electrode film such that the negative electrode contact portion is separated from the transparent electrode film and the positive electrode contact portion; forming an insulating layer on the transparent electrode film such that a light emitting portion is opened; forming an organic light emitting layer on the transparent electrode film and on the insulating layer; and forming a negative electrode layer that is electrically connected to the negative electrode contact portion on the organic light emitting layer such that the negative electrode layer is separated from the transparent electrode film and the positive electrode contact portion, and further comprising: before the forming a negative electrode contact portion, forming a protective layer for electrically insulating the transparent electrode film and the positive electrode contact portion from the negative electrode contact portion between the transparent electrode film and the positive electrode contact portion, and the negative electrode contact portion.
