Abstract:
1. An organic EL light emitting device comprising: a transparent substrate; a transparent electrode film formed on the substrate; a positive electrode contact portion that is electrically connected to the transparent electrode film as a part of the transparent electrode film; an insulating layer formed on the transparent electrode film such that a light emitting portion is opened; an organic light emitting layer formed on the transparent electrode film and on the insulating layer; a negative electrode layer formed on the organic light emitting layer; a negative electrode contact portion that is in contact with at least part of the negative electrode layer and that is electrically connected to the negative electrode layer; and a protective layer that, in order to separate and electrically insulate the transparent electrode film and the positive electrode contact portion from the negative electrode contact portion, is formed therebetween, wherein the positive electrode contact portion and the negative electrode contact portion are electrically insulated by the insulating layer or the protective layer; and the transparent electrode film is formed without a gap across an area on the substrate including areas where the positive electrode contact portion, the insulating layer, the organic light emitting layer, the negative electrode layer, the negative electrode contact portion and the protective layer are formed.
