A method of manufacturing a display device, in particular a security document, includes providing m images of an object, wherein m is at least equal to 2, dividing each image into n sets adjacent arrays (l, l. . . l), . . . , (l, l, . . . l) of picture elements, spaced at a mutual distance δ, applying the images in an interlaced manner on an image layer in sets of interlaced arrays (l, l. . . l), . . . , (l, l. . . l) below a lens structure having line-shaped lens elements over the image layer with one line shaped lens element overlying a corresponding set of adjacent arrays, wherein upon applying the arrays onto the image layer, and/or upon providing the lens elements, each array of picture elements is provided onto the image layer in an out of focus manner to form a blurred array or each array is imaged by the lens elements to form a blurred array, wherein a mutual distance of the edges of adjacent blurred arrays is smaller than the mutual distance δ.
