Abstract
The EL device of the present invention has a structure in which a first electrode, a first insulator layer, an electroluminescence-producing light emitting layer, a second insulator layer, and a second electrode layer are successively stacked on an electrical insulating substrate. At least one of the first insulator layer and the second insulator layer has as a main component barium titanate and in addition 0.1 to 3 mole % magnesium oxide, 0.05 to 1.0 mole % manganese oxide, no more than 1 mole % yttrium oxide, 2 to 12 mole % of barium oxide and calcium oxide, and 2-12 mole % silicon oxide.
