An inorganic, transparent thin film electroluminescent display element with a display area having at least one emissive area and at least one non-emissive area, improved in terms of transparency and inconspicuousness is provided, as well as a method for its preparation. The structure according to the invention comprises a substrate (40), a first conducting layer (42), a first insulating layer (45), a luminescent layer (46), a second insulating layer (47), a second conductive layer (43) and a third insulating layer (44) comprising insulating, inorganic material. Emissive and non-emissive areas of the display are rendered optically similar by providing passive film elements (50) at the non-emissive areas, namely by providing conductor material also at these areas when the conductive electrodes connected to a power source for generating the required voltage are deposited at the emissive areas.
