ABSTRACT:
An EL element includes a) an outer connecting part, b) a substrate comprising a light-transmitting and insulating sheet, c) a light-transmitting electrode layer formed on the substrate wholly or except the outer connecting part in a specific pattern, d) a light emitting layer formed on the light-transmitting electrode layer in a specific pattern, e) a dielectric layer formed on the light emitting layer in a specific pattern, f) a backside electrode layer formed on the dielectric layer in a specific pattern, g) an insulating layer formed on the backside electrode layer and the light-transmitting electrode layer except the outer connecting part, and h) a shielding layer formed on the insulating layer in a specific pattern. The light-transmitting electrode layer or the backside electrode layer is coupled with the shielding layer. The EL element is thus arranged so that it can have its outer connecting part of a reduced size, and so that coupling with the electronic device becomes easy.
