EL SHEET AND SWITCH COMPRISING THE SAME |
摘要 |
<p>An EL sheet is used as a back light of an operating section of various electronic apparatuses. The EL sheet generates a stable click feel and is easily processed. A switch employing the EL sheet is also provided. An EL element layer is not formed at a bent section or its vicinity around a root section of a diaphragm. And only conductive patterns, which are coupled to a light-transmissible electrode layer and a back electrode layer respectively, are formed there. Instead of the conductive patterns, insulating film can be exposed there. <IMAGE></p> |
