A valuable document comprising at least one security element that is provided with a marking layer in a marking region, the layer containing an electroluminescent pigment and being applied to a carrier body. The electroluminescence of the pigment of one such valuable document must be able to be excited even with comparably low, externally applied field intensities. To this end, a plurality of electrically insulated field displacement elements having a minimum dielectric constant of 100 are distributed over the surface of the marking region, the field displacement elements being at a distance of approximately between 5 μm to 500 μm from each other and compressing the applied field in the gaps thereinbetween.
