A variable image-displaying member 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 the row directions and the column directions which are perpendicular to the row directions. 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, between the first static state to shield the first fixed face of the fixed part and the second static state to shield the second fixed face of the fixed part, and which has the second observable face observed by the observer in the first static state, and the first observable face observed by the observer in the second static state, and in the first static state, the second fixed face of the fixed part and the second observable face of the shutter are juxtaposed each other to form the first visible pixel, in the second static state, the first fixed surface of the fixed part and the first observable face of the shutter are juxtaposed each other to form the second visible pixel, the static states of the pixel elements can be determined independently of each other or synchronously with each other, thereby an image composed of a plurality of the visible pixels is displayed. |
