Abstract
Official abstract text for this publication.
A light-emitting element disclosed includes a first electrode layer; a second electrode layer which transmits light; and a light-emitting layer interposed between the first electrode layer and the second electrode layer. The first electrode layer includes a first conductive layer which is able to reflect light, a second conductive layer provided over the first conductive layer and including titanium, and a third conductive layer which transmits light and contains a metal oxide having work function higher than that of a material of the first conductive layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A light-emitting element comprising: a first electrode on a first insulating layer, the first electrode comprising a first conductive layer, a second conductive layer over and directly in contact with the first conductive layer, and a third conductive layer over and directly in contact with the second conductive layer; a second insulating layer over and in contact with the third conductive layer, the second insulating layer comprising an opening portion wh…
