Organic EL panel

An organic EL panel comprising a light-emitting surface and a back surface as opposite main surfaces, the organic EL panel with a shape of a quadrangle comprising a first, second, third, and fourth sides when viewed in plan, the adjacent first and second sides interposing a first vertex therebetween, the organic EL panel comprising a light-emitting region in a center of the light-emitting surface,

• the organic EL panel comprising:
• a first conductive film;
• an organic functional film;
• a second conductive film;
• and
• a sealing film, each of the films being patterned and provided on a substrate in this order toward the back surface of the organic EL panel;
• the organic EL panel further comprising at least a first electrode region and a second electrode stretched region when viewed in plan,
• wherein the first conductive film comprises in the first electrode region:
• a first main body overlapping with the light-emitting region;
• a first electrode pad protruding from the first main body toward the first side;
• a second electrode pad protruding from the first main body toward the second side;
• a third electrode pad protruding from the first main body toward the third side;
• and
• a fourth electrode pad protruding from the first main body toward the fourth side, the first, the second, the third, and the fourth electrode pads being connected continuously through the first main body,
• wherein the second conductive film, when viewed in plan, comprises:
• a second main body overlapping with the light-emitting region;
• and
• a second electrode pad region protruding from the second main body toward the first vertex to reach the second electrode stretched region,
• wherein the sealing film does not overlap with the second electrode stretched region whereas the sealing film overlaps completely with the light-emitting region when viewed in plan,
• the sealing film further covering the second electrode pad region and other part of the organic functional film connected continuously to the organic functional film overlapping with the light-emitting region, and
• wherein the organic EL panel comprises a first electrode conduction path and a circuit board,
• the first electrode conduction path extending, when viewed in plan, to surround at least one half of a periphery of the light-emitting region, so that the first electrode conduction path connects the first, the second, the third, and the fourth electrode pads,
• the circuit board that is fixed near the first vertex comprising a first electrode wire and a second electrode wire,
• the first electrode wire being configured to adhere, in a conductive manner, to the first electrode pad and the second electrode pad,
• the second electrode wire being configured to adhere directly or indirectly, in a conductive manner, to the second electrode pad region in the second electrode stretched region.
