Abstract
First and second insulating layers in an EL device are respectively composed of Al,O,/TiOx:Ba laminated layers. The Al,O,/TiOx:Ba laminated layers are formed by alternately laminating Al,O,layers and TiO,layers added with Ba by an ALE method. Adding Ba into the TiO,layers mitigates a change in resistivity thereof with respect to a change in temperature. As a result, the EL device provides an excellent voltage withstanding performance which is stable against the changes in the temperature.
