ORGANIC EL LIGHT-EMITTING DEVICE

PROBLEM TO BE SOLVED: To provide an organic EL light-emitting device whose dimension can be changed by cutting while achieving its thinning. SOLUTION: The organic EL light-emitting device includes a positive-electrode auxiliary electrode 41 that cross-links between a positive-electrode layer 13 of one of adjacent organic EL cells 10 and a positive-electrode layer 13 of the other of the adjacent organic EL cells 10, and a negative-electrode auxiliary electrode 42 that cross-links between a negative-electrode layer 11 of one of the adjacent organic EL cells 10 and a negative-electrode layer 11 of the other of the adjacent organic EL cells 10. The positive-electrode auxiliary electrode 41 and the negative-electrode auxiliary electrode 42 are arranged so as not to overlap with each other when viewed from the side opposite to the positive-electrode layer 13 side of a light-transmitting film 20. Accordingly, even if the organic EL light-emitting device 1 is cut, the positive-electrode auxiliary electrode 41 and the negative-electrode auxiliary electrode 42 are not short-circuited with each other. Further, it is not necessary to laminate the positive-electrode auxiliary electrode 41 and the negative-electrode auxiliary electrode 42 while sandwiching an insulating layer therebetween, thereby achieving thinning of the organic EL light-emitting device 1.
