Abstract
A display element is rotatably mounted and has a surface portion which includes a nontransparent area and a transparent area, and these two areas are different colors than each other. Such element is mounted behind a front panel having an opening facing the element. By controlling the rotational position of the display element, one of above described areas is selectively displayed. The transparent area can be positioned partly inside and partly outside the front panel, and light from a light source provided inside the front panel can be scattered through the display element.
