Patent number: 8747177Abstract: 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.Type: GrantFiled: February 12, 2013Date of Patent: June 10, 2014Assignee: Sony CorporationInventors: Hirofumi Fujioka, Nobuo Ozawa

Patent number: 8708763Abstract: 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.Type: GrantFiled: August 23, 2012Date of Patent: April 29, 2014Assignee: Sony CorporationInventor: Nobuo Ozawa
