Light-emitting display apparatus incorporating combined first and second auxiliary electrodes arranged at intervals and method of producing the same

A display apparatus includes a display substrate having an element isolation film surrounding peripheral edges of a plurality of first electrodes, and a laminated area composed of a second electrode and auxiliary electrodes and disposed on the element isolation film. Each of the auxiliary electrode is composed of first auxiliary electrodes arranged in a broken line pattern, and second auxiliary electrodes provided on the first auxiliary electrodes so as to cover areas where the first auxiliary electrodes are not provided. A wiring interval between auxiliary electrodes is smaller than a wiring length of an auxiliary electrode, and the film thickness of each of the first auxiliary electrodes is in the range of 5 to 30 nm.
