In an electroluminescent device which is applied to a backlight and a display device and characterized in that a flexible material construction using a plastic substrate is enabled and the device can be produced at a low cost through a relatively simple step without using a vacuum unit and also in that the emission color of the device can be easily controlled by mixing a plurality of fluorescent material particles differing in the emission color or by using a fluorescent dye for the color conversion, the present invention provides a surface emitting-type electro-luminescent device capable of using a low voltage AC power source, realizing uniform brightness and having a large-area emission surface. A surface emitting-type electroluminescent device having a stacked structure in which a transparent electrical conductor layer, a transparent semiconductor layer and/or a transparent insulator layer, a light-emitting layer, a dielectric layer and a back electrode layer are arrayed in this order, the transparent electrical conductor layer, the transparent semiconductor layer, the transparent insulator layer and the dielectric layer each containing a metal oxide.
