A variable image-display having an opaque substrate having a front surface which is observed by an observer, and a back surface opposing the front surface, and a plurality of pixel elements which are arranged on the front surface of the substrate in rows and columns. Each pixel element comprises a fixed part having the first fixed face which is fixed to the front surface of the substrate, the second fixed face adjacent to the first fixed surface, and a border line between the first fixed face and the second fixed face. An opaque shutter which is rotatable around an axis is in parallel with the border line between the fixed faces such that in a first static state, the second fixed face of the fixed part and the second observable face of the shutter are juxtaposed to form a first visible pixel, in a second static state, the first fixed surface of the fixed part and the first observable face of the shutter are juxtaposed to form a second visible pixel. The static states of the pixel elements can be determined independently of each other or synchronously with each other, thereby variable imaged may be displayed. |
