Abstract: An organic EL device capable of preventing a deterioration in luminous section and increasing an effective area of a luminous section and current gain thereof. The organic EL device includes at least one first electrode made of a transparent electrode material, at least one luminous section made of an organic EL material and formed on the first electrode, and at least one second electrode formed on the luminous section. The luminous section is arranged on the first electrode so that the first electrode has an annular upper surface portion which is not covered with the luminous section left on an upper surface thereof in a manner to surround the luminous section. The second electrode is formed so that the luminous section has an annular upper surface portion which is not covered with the second electrode left on an upper surface thereof in a manner to surround the second electrode. The organic EL device also includes at least one insulating side wall structure made of an insulating material, formed into an annular shape and arranged so as to cover the annular upper surface portion of the first electrode, an outer peripheral side surface of the luminous section, the annular upper surface portion of the luminous section and an outer peripheral side surface of the second electrode. The organic EL device also includes an insulating protective layer formed of an insulating material so as to cover the insulating side wall structure and an exposed portion of the first electrode and provided with holes through which an upper surface portion of the second electrode is exposed and at least one third electrode formed on the insulating protective layer and connected to the second electrode through the holes of the insulating protective layer.

Abstract: An organic EL device capable of providing an image plane which exhibits increased luminance or brightness while eliminating any difference in luminescence between luminous sections. An electrically insulating layer is arranged so as to cover both a first wiring pattern and a second wiring pattern and formed with a plurality of hole arrays in a manner to respectively correspond to first electrodes. The hole arrays each are constituted of a plurality of holes arranged along the first electrode corresponding thereto and so as to extend through an insulating layer to the first electrode while being kept from extending through second electrodes. A third wiring pattern is arranged which is constituted of a plurality of conductive paths each arranged on the insulating layer so as to be in alignment with each of the hole arrays and electrically connected to each of the first electrodes through connection conductive sections formed in the holes of the hole array corresponding thereto. An organic EL device capable of providing an image plane which exhibits increased luminance or brightness while eliminating any difference in luminescence between luminous sections. An electrically insulating layer is arranged so as to cover both a first wiring pattern and a ...more ...less
