Abstract

Official abstract text for this publication.

Organic light emitting diode display device including a substrate covered by a cover which has a plane surface delimited along the external perimeter thereof. The plane surface of the cover is provided with a protuberance. The substrate is provided with a stack of layers, the stack of layers including at least the following layers in succession in the following order starting from the substrate: at least one anode; an insulating layer; a spacer layer which has a first exclusion area in a first area; an active hole injection layer, an active hole transport layer and an active electron transport layer; a cathode layer which has a second exclusion area. The protuberance of the cover is joined to the layer with which the protuberance is in contact, a hole, whose diameter is smaller than the geometrical dimensions of the protuberance, being made in the protuberance and through the substrate.

First claim

Opening claim text (preview).

What is claimed is: 1. An organic light emitting diode display device, comprising: a substrate covered by a cover which has a plane surface delimited along the external perimeter thereof by an edge, via which the cover is secured to the substrate, wherein the plane surface of the cover is provided with a protuberance which extends in the direction of the substrate, wherein the substrate is provided with a stack of layers including at least the following layers which succeed ea…
