ORGANIC EL MODULE AND POWER SUPPLY STRUCTURE MADE UP OF ORGANIC EL MODULES

摘要

The present invention aims at providing a further downsizable organic EL module. Void parts are formed on first and second power supply members. The power supply members are different in shape, so that at least a part of the first power supply member is located in a vertically projected region of the second void part and at least a part of the second power supply member is located in a vertically projected region of the first void part when the power supply members overlap with an insulation layer sandwiched between. An electric wire penetrates the second power supply member to be connected to the first power supply member. The first power supply member is connected to one electrode layer directly or via a conducting member. The second power supply member, to which another electric wire is connected, is connected to another electrode layer directly or via a conducting member.

主权项

1. An organic EL module incorporating an organic EL device having a layer structure formed of at least a first electrode layer, an organic light-emitting layer, and a second electrode layer and stacked on a substrate having a planar expanse, wherein the substrate has sides or a peripheral part, the organic EL module comprising:
a first power supply member; an insulation layer; a second power supply member; and at least two electric wires, the first power supply member and the second power supply member each having a plate or foil shape and having an outer edge part and an edge end, the first power supply member and the second power supply member having a first power supply member void part and a second power supply member void part formed by cutting out a part of the members, respectively, the first power supply member and the second power supply member being different in shape from each other, wherein the organic EL device has a light emitting part, at least a part of the first power supply member being located in a region where the second power supply member void part is projected in a member thickness direction of the light emitting part and at least a part of the second power supply member being located in a region where the first power supply member void part is projected in a member thickness direction of the light emitting part when the first power supply member and the second power supply member overlap, the first power supply member and the second power supply member overlapping each other with the insulation layer sandwiched therebetween, one of the electric wires penetrating the second power supply member being connected to the first power supply member, the first power supply member, to which the one of the electric wires is connected, being connected to one selected from a group consisting of the first electrode layer and the second electrode layer either directly or via a conducting member, and the second power supply member, to which the other of the electric wires is connected, being connected to the other selected from the group consisting of the first electrode layer and the second electrode layer either directly or via a conducting member.
