| 摘要 |
Electroluminescent elements of high light intensity and long useful life, operating at comparatively low energy input, are obtained by directly bonding to a supported web of thin plastic film without intermediate adhesive a layer of resin containing EL phosphor thoroughly and uniformly dispersed therein, and depositing on the surface of said resin a fine layer of a transparent electrode consisting essentially of indium tin oxide. In alternative embodiments the said resin layer is sandwiched between thin deposited layers of alkaline earth metal titanate.
