  • 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.
