The present invention details a group of focussed means to create points of light of different sizes and colours, that together form figures whose function is to create a sign in front of the eyes of a driver or operator, to provide them with certain information from a remote point. The points of light are created by the ionization of the air in different points in the space where it is desirable to create the sign in question.

A display device includes a display plate, a micro light source, a first reflecting element and a second reflecting element. The display plate has a pattern. The micro light source emits a light beam. The first reflecting element is arranged beside a first side of the display plate. A first portion of the light beam is reflected by the first reflecting element. A second portion of the light beam is transmitted through the first reflecting element. The second reflecting element is arranged beside a second side of the display plate to reflect the light beam. The light beam is repeatedly reflected by the first reflecting element and the second reflecting element, so that a multiple-luminous effect of the pattern is provided.

In an optical structure for displaying a stereoscopic frame image on a structure formation surface, a frame motif that displays a frame image in which reflection moves is formed on a structure formation surface, the frame motif is made up of a plurality of perforated reflecting segments, each including one or more first reflecting mirrors having a reflective layer uniformly tilted relative to the structure formation surface, the tilt angle of the first reflecting mirror is different between adjacent perforated reflecting segments so as to gradually change over a plurality of adjacent perforated reflecting segments, and at least one of the plurality of perforated reflecting segments surrounds an opening provided with no first reflecting mirror.
