Abstract

PURPOSE:To improve luminance efficiency and element characteristic by forming a light emitting layer, consisting of sulfide of alkali-earth element activated with Eu, with mixed crystals of MgS and CaS. CONSTITUTION:An EL element is formed by forming a film of a transparent electrode 2 and a 1st insulation layer 3 on a glass substrate 1, forming over them a light emitting layer 4 with the composition of Mg1-xCaxS where the value of x is 0<x<=0.9, further forming over the light emitting layer 4 a 2nd insulating layer 5 and an Al electrode 6. With this constitution, both luminance and efficiency characteristic are improved while maintaining good color purity by using the mixed crystal of MgS and CaS as materials for the light emitting layer 4 consisting of alkali-earth sulfide activated with Eu.
