Abstract
An electroluminescent device including a transparent substrate, a securing layer, a light scattering layer, an electroluminescent unit including a transparent electrode layer, a light emitting element including at least one light emitting layer, and a reflecting electrode layer in that order, wherein the light scattering layer includes one monolayer of inorganic particles having an index of refraction larger than that of the light emitting layer and wherein the securing layer holds the inorganic particles in the light scattering layer.

32. A method for providing an electroluminescent device comprising:
-
(a) providing a carrier having at least one smooth surface; (b) disposing a scattering layer comprising a monolayer of scattering particles over the smooth surface of the carrier; (c) providing a substrate in relative position to the carrier and dispensing a quantity of the securing material between the substrate and the carrier; (d) engaging the substrate and the securing material to form the securing material into a layer between the substrate and the scattering layer; (e) separating the substrate with the attached securing layer and the scattering layer from the carrier; and (f) forming the electroluminescent unit on the light scattering layer. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 42)
