    摘要： All of a transparent electrode layer 2, a light-emitting layer 3, a dielectric layer 4, a back-surface electrode 5, collecting electrodes 5a, 5b, and an insulating coat layer 6 are laminated with predetermined patterns by screen printing on a insulating transparent film 1. Conductive paste used for forming transparent electrode layer 2 comprises conductive powder of indium oxide which contains needle-like powder (A) and fine-grain powder (B) at a blending ratio of (A):(B)=100:0 to 20:80. A binder resin (D), being a photo-hardening or thermal-hardening resin, is mixed with the conductive powder (C) at a blending ratio of (C):(D)=45:55 to 95:5, thereby obtaining an excellent EL lighting element. In an illuminated switch unit, a switch operating projection 14 is provided on the reverse surface of an EL lighting element 15 and this EL lighting element 15 is fixed above a membrane switch 13 via a spacer 16, thereby removing any obstacles interrupting or intercepting illumination light emitted from EL lighting element 15.

    摘要： A dispersion electroluminescent device and a switch unit using the same are disclosed. The dispersion electroluminescent device includes three electrodes: first and second electrode layers and a common electrode layer. The common electrode layer is disposed between the first and second electrode layers. An electroluminescent layer and a first dielectric layer are disposed between the first electrode layer and the common electrode layer. A second dielectric layer is disposed between the common electrode layer and the second electrode layer. A voltage source applies first and second ac or dc pulse voltages, which are 180.degree. out of phase with each other, across the first electrode layer and the common electrode layer and across the common electrode layer and the second electrode layer, respectively, for canceling mechanical vibrations produced at the first and second dielectric layers by each other.
