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.
Claims11
A method of manufacturing a light-emitting display comprising the steps of:
- forming a drive element and a first wiring layer over a substrate, and electrically connecting the plurality of drive elements and the wiring layer;
- forming a first conductive layer over the drive elements and the wiring layer;
- forming a first electrode corresponding to the plurality of drive elements, respectively, as well as an auxiliary wiring layer by patterning the first conductive layer;
- forming a respective light emission section on each of the first electrodes;
- forming a common second electrode of a material allowing light from each light emission section to pass therethrough on the plurality of the light emission sections;
- and
- forming a conductive contact layer, and electrically connecting the common second electrode and the auxiliary wiring layer through the conductive contact layer,
- wherein,
- a portion of the common second electrode is in direct contact with the conductive contact layer, and a portion of the auxiliary wiring layer is positioned above and in direct contact with the conductive contact layer.
