Abstract
Official abstract text for this publication.
The organic electroluminescence display device has a laminated portion on a base substrate. The device may have a cavernous portion formed by exploding a part of the laminated portion in a screening processing. A protective layer is formed to cover a whole surface of a wall defining the cavernous portion. Therefore, substances contained in the air are prevented from contacting to an organic electroluminescence layer at least partially defining the cavernous portion. Therefore, even if moisture is contained in the air, it is possible to prevent moisture from being absorbed by the organic electroluminescence layer. Moreover, since moisture is not absorbed by the organic electroluminescence layer, it is possible to reduce irregular spot on the device. In addition, it is possible to reduce a short circuit at an open defective portion.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic electroluminescence display device, comprising: a base substrate; a multilayer laminate formed on the base substrate, the multilayer laminate comprising a lower electrode layer, an organic electroluminescence layer and an upper electrode layer; and the multilayer laminate having a broken surface, the broken surface containing a cavernous-shaped broken portion having a cavity comprising: a crater contained within the multilayer laminate and free…
