Abstract
A dispersion-type EL device includes a short-bar contact, a first insulating layer, a back electrode layer, a dielectric layer, a luminescent layer, and an optically transparent electrode layer, which are sequentially formed on a temporary substrate that has been processed with an exfoliation treatment. This configuration realizes a reduction in size in a thickness direction. Furthermore, an illuminated switch unit is provided, in which a dispersion-type EL device peeled off from a temporary substrate and a wiring board having a comb-like contact are connected to each other.
