Abstract
A thin-film electroluminescent device includes dielectric layers having improved dielectric characteristics. The device is fabricated by forming a first transparent electrode layer of ITO, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer of ITO in this order on an insulating substrate. Each of the two dielectric layers is a film constituted by TaSnON. That is, the film includes tantalum, tin, oxygen, and nitrogen.
