Title:
ORGANIC EL ELEMENT AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2004/075607
Kind Code:
A1
Abstract:
An organic EL element not likely to be deteriorated in TFT characteristics even if a pixel electrode is irradiated with a ultraviolet ray. A TFT, formed on a substrate, has a first region and a second region serving as a source and a drain, a channel region between the first and second regions, and a gate electrode. An interlayer insulation film is disposed on a substrate so as to cover the thin film transistor. A pixel electrode disposed on the interlayer insulation film is electrically connected to the first region of the TFT through a via hole formed in the interlayer insulation film. A coating film covers the edge of a pixel electrode with the interior region kept exposed, and also covers the region, overlapping the channel region of the above thin film transistor, of the surface of the interlayer insulation film to shield a ultraviolet ray. An organic light emitting layer and an upper electrode are disposed on a pixel electrode.
