Abstract

A method for manufacturing an organic electroluminescence display including multilayer structures that are each formed in a respective one of pixel areas in an effective area of a substrate and are each formed by a lower electrode, an organic layer, and an upper electrode, the organic electroluminescence display having a common electrode that electrically connects the pixel areas, the method including the steps of: forming a protective electrode and an outer-peripheral electrode that are electrically connected to the common electrode; forming the multilayer structures; and carrying out film deposition treatment involving electrification of the substrate.

Claims (9)

1. An organic electroluminescent display apparatus, comprising:

a substrate with a light emission region and a peripheral region around a periphery of the light emission region;

a plurality of pixels within the light emission region, the light emission region including a lower electrode, an upper electrode, and an organic layer between the lower and upper electrodes;

an outer-peripheral electrode located outside of the light emission region and the peripheral region;

a protective film covering an upper face of the upper electrode; and

a protection electrode electrically connected to the outer-peripheral electrode and to a common electrode and ensuring conduction of charge generated by formation of the protective film to a region outside of the peripheral region,

wherein,

the upper electrode is a blanket film that covers the pixels and functions as a part of the common electrode.

2. An electronic equipment comprising the organic electroluminescent display apparatus of claim 1 .
