Abstract (en)
An electroluminescent (EL) device for displaying a full color image includes a substrate, e.g., made of glass, a thick-film EL layered structure including a blue light emitting thick-film EL layer, e.g., made of ZnS:Cu and a thin-film EL layered structure including a red light emitting thin-film EL layer, e.g., made of CaS:Eu. In the EL device, the thick-film EL layered structure is formed on either top or bottom of the substrate and the thin-film EL layered structure is formed either on top of the thick-film EL layered structure or on top of the substrate. In the EL device, a green light emitting EL layer is included either in the thick-film EL layered structure as a green light emitting thick-film EL layer, e.g., made of ZnS:Tb or ZnS:Cu, or in the thin-film EL layered structure as a green light emitting thin-film EL layer, e.g., made of ZnS:Tb. The EL device is capable of providing a blue light, a green light and a red light concurrently, each light having a commercially acceptable brightness level to thereby, allowing the EL device to display a full-color image having a commercially acceptable brightness level. <IMAGE>
