Abstract
PURPOSE:To allow the low-voltage drive by forming the first insulating layer with a film containing a perovskite crystal structure and having a high dielectric constant. CONSTITUTION:A thin film mainly made of CaTiO3 or SrTiO3 or KTaO3 and containing a perovskite crystal structure and having a high dielectric constant is used at least for the first insulating layer 3 of a thin film electroluminescence element provided with insulating layers 3 and 5 and a luminous layer 4 between a pair of electrodes 2 and 6. The dielectric constant is about 80-150 and very high, thus the voltage applied to the element is almost applied to the luminous layer 4. It can be thereby driven by the low voltage.
