1. A security element for manufacturing value documents, comprising:
a structure presenting a first and a second motif, which change their appearance when the security element is tilted over a tilting angle range,
wherein the structure has first micro-elements, which are arranged according to a first pattern and present the first motif, and second micro-elements, which are arranged according to a second pattern and present the second motif, and
wherein the first and the second pattern are nested within each other on an areal region of the security element,
wherein the first micro-elements present the first motif in such a manner that the first motif is visible in its entirety in the areal region within the tilting angle range at a certain start tilt position and, when the tilt position changes, is still visible only in a portion of the areal region which decreases as the tilt increases and, upon reaching a certain end tilt position, is no longer visible at all, and
wherein the second micro-elements present the second motif only in the rest of the areal region remaining in relation to the portion of the areal region,
wherein the second motif is not visible at all in the areal region at the start tilt position and is visible in its entirety in the areal region at the end tilt position,
wherein the first and second micro-elements have micromirrors,
wherein the micromirrors are arranged and a gradient of the micromirrors is configured such that spatial sub-regions of the first and second motifs each have different viewing angle ranges.
