Abstract
A light-emitting display capable of maintaining low power consumption and improving display quality irrespective of the configuration of an auxiliary wiring is provided. A second electrode 20 and an auxiliary wiring 18B are electrically connected to each other through a conductive contact section 15B. Moreover, only a part of the auxiliary wiring 18B is connected to the contact section 15B. Even if the surface of the auxiliary wiring 18B 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 15B.
