ORGANIC EL DISPLAY APPARATUS
First Claim
1. An organic EL display apparatus, comprising:
- a substrate;
an insulating film formed on the substrate and having a plurality of openings at equal intervals; and
a plurality of organic EL devices formed in the openings on the substrate and each constituting a light-emitting portion, the organic EL devices each comprising a first electrode patterned for each of the light-emitting portions;
an organic EL layer formed on the first electrode; and
a second electrode formed continuously on the organic EL layer so as to extend over the light-emitting portions, an edge portion of the first electrode being covered by the insulating film,wherein the organic EL layer is formed on an inner side than the opening located at an outermost periphery, and wherein in the opening located at an outer periphery of the organic EL layer, a layer which is the same as the first electrode and the second electrode are in contact with each other.

Abstract
Provided is an organic EL display apparatus which can prevent, moisture in a planarizing film or outside moisture intruding into the planarizing film, from intruding into a light-emitting portion through a cracked portion of an insulating film, thereby suppressing peripheral degradation. The organic EL display apparatus includes a substrate, an insulating film formed on the substrate and having a plurality of openings at equal intervals, and a plurality of organic EL devices formed in the openings on the substrate and each constituting a light-emitting portion, in which the organic EL layer is formed on an inner side than the opening located at an outermost periphery, and in which in the opening located at an outer periphery of the organic EL layer, a layer which is the same as the first electrode and the second electrode are in contact with each other.
