Abstract: A first finger electrode group including finger electrodes on the first principal surface. A second finger electrode group including finger electrodes on the second principal surface. The second finger electrode group is divided into divided electrode portions, the number of electrodes of the electrode portions decreasing as a distance from a central portion of the second finger electrode group increases towards outside, and a coupling portion is arranged between each adjacent ones of the divided electrode portions and electrically connects at least two of the finger electrodes of the divided electrode portion on inside with at least one of the finger electrodes of the divided electrode portion on outside. The number of finger electrodes of the divided electrode portion closest to the central portion of the second finger electrode group is larger than the number of finger electrodes of the first finger electrode group.

Abstract: A plurality of organic EL devices are formed first on a substrate. Next, a film of a sealing agent is formed over the outer periphery of a lower surface (color filter side) of a sealing plate. Then, a sealing agent is dropped onto a central portion of the sealing plate. After that, the sealing plate and the substrate are laminated at a predetermined pressure in a vacuum chamber in a vacuum, and then the vacuum chamber is released from its vacuum state. The substrate and the sealing plate are removed from the vacuum chamber, and the sealing agents between the substrate and the sealing plate are cured by the curing methods suitable for the respective materials.
