Abstract

Disclosed is an electroluminescence device having a substrate, a thin film transistor over the substrate, an insulating film over the thin film transistor, an electroluminescence element over the insulating film, a passivation film over the electroluminescence element, and a counter substrate over the passivation film. The electroluminescence element is configured to emit light through the counter substrate, and a space between the substrate and the counter substrate is filled with a filler. The electroluminescence device is featured by the tapered side surface of a gate electrode of the thin film transistor.
