ABSTRACT:
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 an 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-gain 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.
