PROBLEM TO BE SOLVED: To solve four problems (problems of a shape of a light emitting surface, flexibility, heat dissipation, and color rendering properties) which are inherent in current flat substrate techniques, when an organic EL light emitting diode is applied for a lighting system.SOLUTION: A transparent, flexible and long plastic tape 12 configures a linear and flexible one-dimensional anode substrate in which a graphene film 14 is formed, as a transparent electrode, on the whole area of a smooth surface, and a metal electrode 15 is formed on a side face to be in electrical contact with the graphene film 14. An organic EL layer 16 and a cathode electrode 17 are laminated on the graphene film 14. A sealing structure is a structure where an insulating adhesive layer, which is formed at a width direction end part of a one-dimensional cathode substrate comprising metal films 23, 24 formed on both sides of a long plastic tape 22, is deformed by following the one-dimensional anode substrate 11 in bonding to seal the organic EL layer 16 and the graphene film with a sealing portion 42. |
