The high refractive dielectric film which can be used stably as a constituent material of an optical multi-layer film, namely, and which does not cause change over time in optical properties and has small film stress, is an amorphous material having no columnar structure, obtained by adding to a main component titanium oxide (TiOx: 1&#x2266;x&#x2266;2) another metal oxide (MOw: M represents a metal such as niobium, tantalum, 1&#x2266;w). Though titanium oxide is a material which tends to manifest a crystalline structure even in the form of a thin film, a mixed high refractive dielectric film can be obtained, containing titanium oxide causing little change over time in optical properties by rendering the resulting thin film amorphous by inhibiting growth of a crystal of titanium oxide by adding another metal oxide.

An electroluminescence device is constituted by sequentially stacking a glass substrate, a transparent electrode, a luminescent layer, an interlayer containing a semiconductor having a band gap of 2.4 eV or more, a current-limiting layer containing a conductive powder, and a backplate.
