发明名称 ELECTRO-LUMINESCENT DEVICE
摘要 An EL element having a layered ceramic product comprising a substrate, a fir st electrode layer and a first insulation layer, and using in at least one of insulation layers a dielectric material of a specified composition mainly consisting of MgO: 0.1 to 3 mol%, MnO: 0.05 to 1.0 mol%, Y2O3: up to 1 mol%, BaO + CaO: 2 to 12 mol%, SiO2: 2 to 12 mol% per 100 mol% of BaTiO3, whereby producing an EL element capable of a low-voltage drive, hardly causing dielectric breakdown and providing a stable, extended-time light emission.</ SDOAB>
