Abstract
An electroluminescent display device is formed by superposing a support member, a first electrode layer, a light-emitting layer, a second electrode layer which transmits light and a color conversion filter layer in this order. The light-emitting layer is formed by dispersing electroluminescent light-emitting particles which emit a predetermined color of light in a dielectric binder. The color conversion filter layer includes color conversion portions and/or transparent portions which transmit light. The first electrode layer and the second electrode layer form an X-Y matrix electrode. Further, the EL light-emitting layer is uniformly formed over the entire area of the electroluminescent display device.
Claims8
An electroluminescent display device comprising:
- a support member;
- a first electrode layer;
- a plane-shaped light-emitting layer;
- a second electrode layer which transmits light;
- and
- a color conversion filter layer, wherein the plane-shaped light-emitting layer is formed by dispersing electroluminescent light-emitting particles which emit a predetermined color of light in a dielectric binder, and wherein the color conversion filter layer includes a multiplicity of color conversion portions which convert the color of the light and/or a multiplicity of transparent portions which transmit the light, and wherein the support member, first electrode layer, plane-shaped light-emitting layer, second electrode layer and color conversion filter layer are superposed in this order, and wherein each of the first electrode layer and the second electrode layer includes a plurality of line-shaped electrodes, and wherein the plurality of line-shaped electrodes of the first electrode layer and that of the second electrode layer cross each other, and wherein the plane-shaped light emission layer is uniformly formed over the entire area of the electroluminescent display device.
