Abstract: In display comprising a display surface member with a plurality of display surfaces, and a permanent magnet type motor mechanism composed of a stator having magnetic members each forming a magnetic pole at one free end and excitation windings wound on the magnetic members and a rotor having a magnet member with a double-pole permanent magnet, the number of display surfaces of the display surface member is three or more odd number; the numbers of magnetic members and excitation windings of the rotor are also odd in accordance with the number of display surfaces and the magnet member of the rotor has a first magnetic pole opposed to the magnetic pole of one of the odd number of magnetic members and a second magnetic pole opposed to the magnetic poles of the other two adjacent magnetic members.

Abstract: A pseudo-luminous panel has a substrate and a thin film optical color filter formed all over the main surface of the substrate with or without a reflecting film interposed therebetween. The main surface of the substrate is formed by obliquely downward and upward band-like surfaces alternately arranged side by side in a vertical direction. The downward band-like surfaces of the substrate, or downward band-like surfaces of the reflecting film formed on the downward band-like surfaces of the substrate are each a smooth reflecting surface. The upward band-like surfaces of the substrate, or the upward band-like surfaces of the reflecting film formed on the upward band-like surfaces of the substrate, are each a smooth, irregular or uneven reflecting surface. Obliquely downward band-like surfaces of the color filter are each a smooth surface extending straight in the longitudinal section of the panel, and obliquely upward band-like surfaces of the color filter are each a rough surface.

Abstract: A pseudo-luminous panel has an optical color filter and a reflecting film formed all over the back thereof. The surface of the optical color filter is formed by obliquely downward and upward band-like surface portions alternately arranged side by side in the vertical direction. The back face of the optical color filter is has obliquely upward band-like back face portions each on the opposite side from one of the obliquely downward band-like surface portions and obliquely downward band-like back face portions each on the opposite side from one of obliquely upward band-like surface portions. The obliquely downward band-like surface portions of the optical color filter are each a smooth surface extending straight in the longitudinal section of the panel. The obliquely upward band-like surface portions of the optical color filter are each a rough surface. The obliquely upward band-like back face portions of the optical color filter are each a smooth surface.

The display elements are each formed with a plate-like (or four-cornered) block member having two (or four) display surfaces of different colors and one (or three) magnetic pieces. A selected one or ones of the display elements are rotated by the movement of a display control head or heads and by temporary energization of one (or three) magnets of each head to make a selected one of the two (or four) display surfaces of the selected display elements face forwardly, providing a display of a character, graph, pattern or the like on the display surface structure.
