Abstract:
A method for manufacturing an inorganic thin film electroluminescent display element comprises forming a layer structure, said forming the layer structure comprising forming a first dielectric layer (11); forming a luminescent layer (12), comprising manganese doped zinc sulfide ZnS:Mn, on the first dielectric layer, and forming a second dielectric layer (13) on the luminescent layer. Each of the first and the second dielectric layers are formed so as to comprise nanolaminate with alternating aluminum oxide Al2O3 and zirconium oxide ZrO2 sub-layers.
