Patent ID: 8421347

Claim:
An integrated organic light-emitting device comprising a laminated body consisting of a light-transmissive first electrode layer, a laminated layer containing at least one organic EL emission layer composed of an organic compound, and a second electrode layer laminated on a light-transmissive insulated substrate, the device having at least one first-electrode-layer dividing groove formed in the first electrode layer, at least one via formed in the laminated layer, and at least one unit light-emitting-element dividing groove having a depth reaching the second electrode layer from the laminated layer, wherein the first electrode layer is divided into a plurality of zones by the first-electrode-layer dividing grooves, wherein the laminated layer and the second electrode layer are divided into a plurality of zones each composed of a combination of the both layers by the unit light-emitting-element dividing grooves, wherein the first-electrode-layer dividing grooves and the unit light-emitting-element dividing grooves are located at different positions so that at least the second electrode layer of one zone overhangs the first electrode layer of its adjacent zone, wherein the first electrode layer in one zone and the combination of the laminated layer and the second electrode layer laminated on the first electrode layer in the one zone constitutes a unit light-emitting element, in which a part of the second electrode layer penetrates in the via so as to be electrically conducted to the first electrode layer in its adjacent zone, so that adjacent elements are electrically connected in series, and wherein the unit light-emitting-element dividing groove is formed by a number of continuous small holes, each hole having a shape increasing in diameter from the substrate toward the second electrode layer, so that at least the second electrode layer is divided by the holes, which overlap, and the first electrode layer has a conductive part between the holes, which do not overlap.
