Patent ID: 7432648

Claim:
An electroluminescent (EL) display, comprising: a transparent substrate; an anode; a cathode; and an electroluminescent (EL) layer interposed between the anode and the cathode, wherein the EL layer comprises a light emitting layer that emits light when the anode and the cathode are electrically driven, wherein the anode and the cathode are each formed as a translucent conductive layer that partially reflects the light emitted from the light-emitting layer, wherein the anode comprises a first transparent conductive layer that transmits light and a first partially reflective layer that partially reflects light, and the cathode comprises a second transparent conductive layer that transmits light and a second partially reflective layer that partially reflects light, wherein the first transparent conductive layer comprises a first inner transparent conductive layer and a first outer transparent conductive layer, the first partially reflective layer being formed therebetween, and the second transparent conductive layer comprises a second inner transparent conductive layer and a second outer transparent conductive layer, the second partially reflective layer being formed therebetween, and wherein the first partially reflective layer and the second partially reflective layer have a light transmittance of 40% or more and a light absorptivity of less than 30%.
