Abstract

A display apparatus includes a substrate, a plurality of pixels formed on the substrate, and a barrier plate for separating adjoining pixels from each other. Each pixel includes a lower layer portion having wiring formed on the substrate, an upper layer portion having an organic electro-luminescent element, and a middle layer portion for insulating the lower layer portion and the upper layer portion from each other electrically. The organic electro-luminescent element is connected with the wiring through a contact hole formed in the middle layer portion. The barrier plate is disposed in the upper layer portion so as to overlap with a region including a contact hole not suitable for forming the organic electro-luminescent element.

Dependent claims

A display apparatus including a substrate, a plurality of pixels formed on said substrate, and a barrier plate for separating adjoining pixels of said pixels from each other, wherein:

each of said pixels comprises a lower layer portion including a wiring formed on said substrate, an upper portion including an organic electro-luminescent element, and a middle layer portion for electrically insulating said lower layer portion and said upper layer portion from each other, and
said organic electro-luminescent element is connected with the wiring through a contact hole formed in said middle layer portion, and further
said barrier plate is disposed in said upper layer portion so as to overlap with a region including the contact hole and said barrier plate is not in physical or electrical contact with at least one of said organic electro-luminescent element and said anode.
