  • Patent number: 8747177
    Abstract: A light-emitting display capable of maintaining low power consumption and improving display quality irrespective of the configuration of an auxiliary wiring. A second electrode and an auxiliary wiring are electrically connected to each other through a conductive contact section. Moreover, only a part of the auxiliary wiring is connected to the contact section. Even if the surface of the auxiliary wiring is oxidized, an increase in connection resistance is prevented. Moreover, a restriction on layout is not imposed at the time of forming the contact section.

  • Patent number: 8708763
    Abstract: A laminated structure formed by placing a cover substrate over a device substrate with a projection structure in between in the vacuum atmosphere. Next, the laminated structure is taken out into the air in a state that a space between the device substrate and the cover substrate is maintained in the vacuum atmosphere. Subsequently, the portion of the organic layer formed on the conductive electrode is removed by irradiating laser light to the laminated structure. Since the space between the device substrate and the cover substrate is maintained in the vacuum atmosphere, even if the laser light is emitted to the laminated structure taken out into the air, the laser light is emitted to the portion of the organic layer formed on the conductive electrode in the vacuum atmosphere.

  • Publication number: 20120104942
    Abstract: A display device and a method for manufacturing the display device are provided. The display device includes an organic layer on an auxiliary wiring is removed with high precision by one operation and, thereby, the yield and the productivity are improved. A lower electrode is formed by patterning in each pixel on a substrate. An auxiliary wiring including a light absorption layer is formed between individual pixels. An organic layer is formed on the substrate while covering the lower electrodes. Laser irradiation is conducted from the organic layer side, the laser light is converted to heat in the light absorption layer exposed at a portion under the organic layer, and the organic layer portion above the light absorption layer is removed selectively. An upper electrode is formed on the organic layer and is connected to the light absorption layer portion of the auxiliary wiring.
