  • Patent number: 9386656
    Abstract: The present invention aims to provide a luminescent system enabling contactless power supply, having a high ratio of light emission region, and securing a desired quantity of emitted light. The luminescent system is constituted by an organic EL device and a fixed-side wall surface. The device is formed by stacking an electrode layer of an anode side, an organic light-emitting layer, and a transparent electrode layer of a cathode side on a substrate and being sealed by a sealing part. Electrodes with a planar expanse are stacked on a face near the wall surface and are arranged so as to overlap a light emitting region where the organic light-emitting layer is disposed. Electrodes with a planar expanse are embedded in the wall surface. A power unit is electrically connected between the electrodes. The electrodes of the device and of the wall surface are opposite each other across a flooring material.

  • Patent number: 8987726
    Abstract: Provided is a high-luminance, long-life laminated organic electroluminescent element. The organic electroluminescent element has a composition in which a plurality of light-emitting units, including at least one organic light-emitting layer, are laminated between a positive electrode and a negative electrode, and in which a linking layer is held between the respective light-emitting units. The linking layer is formed by laminating, in succession from the positive electrode side, an electron generating/transport section, an intermediate layer, and a hole generating/transport section, which contain at least one metal selected from a group consisting of an alkali metal, alkaline earth metal, rare earth metal, alloy of these metals, and compound of these metals. Preferably the intermediate layer contains an electrical insulating non-semiconductive substance having a specific resistance which is between 1.0×102 ?·cm and 1.0×109 ?·cm.
