Abstract:
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.
