ABSTRACT:
A thin film electroluminescence display element composed of a soda-lime glass substrate having provided thereon a barrier layer including tantalum (V) oxide, a transparent indium-tin oxide (ITO) electrode as a first electrode, a first insulating layer, a luminescent layer, a second insulating layer, and a second electrode is disclosed. The tantalum (V) oxide barrier layer effectively prevents sodium in the soda-lime glass substrate from diffusing into the ITO transparent electrode.
