Abstract: PURPOSE:To provide a display object which protects the display surface with a light guide having excellent impact resistance and can be installed on a floor or the like, and a light guide using a honeycomb construction. CONSTITUTION:It is a feature of this light guide 2 that light transmitting resin is filled in the hollow part of a honeycomb structure, the display object is featured so that the light guide 2 with light transmitting resin filled in the hollow part of the honeycomb structure is placed on the display surface of a flat panel display 1, and in the case it is featured that a light transmitting carpet is further laid on the light guide 2. The display surface is protected by means of the light guide 2 of honeycomb construction, and hence the display object of which safety and durability are excellent and in addition the display can be clearly read can be obtained. Further, the light guide 2 of new honeycomb construction can be obtained.

Abstract: PURPOSE:To provide an optical element formed by utilizing assemblies of fibers as two sheets of sheet-like materials and the display plate of a transmission type or reflection type arranged therewith. CONSTITUTION:This optical element 8 consists of two sheets of the sheet-like materials and has the structure in which at least one sheet thereof is a driving part and is fixed to a fixing part 3 of plural band-shaped electrodes 2 and an insulator 4. The optical element is driven by the electrostatic attraction and repulsion force generated between the driving part and the fixing part when a voltage is impressed to the band-shaped electrodes 2. The sheet-like materials constituting the driving part are the assemblies of the fibers. The display element is constituted by arranging a plurality of these optical elements. The constitution is simple and the thin film-like flexible optical elements having a memory characteristic are obtd. The sheet-like flexible display plate which is formable to a large size and is bendable and roundable is obtd. An effect like that of ground glass is obtd.

Abstract: PURPOSE:To provide the display device of a transmission type or reflection type which is reloadable and is easily formable to a larger size by utilizing two sheets of light transmission plates and electrostatic attraction and repulsion force. CONSTITUTION:This display device is composed of a display section 1 which is arranged with pixels consisting of two sheets of the light transmission plates, a printing erasure head 3 and a scanning section 4 which relatively moves this printing erasure head 3 along the display section 1. The printing erasure head 3 consists of an insulator arranged with plural band-shaped electrodes. At least one sheet of the light transmission plates is driven by the electrostatic attraction and repulsion force generated between the light transmission plates and the printing erasure head 3 when a voltage is impressed to the band-shaped electrodes, by which printing and erasing of the display are executed. As a result, the display device of the transmission type or reflection type which is reloadable and is easily formable to a larger size is obtd.

Abstract: PURPOSE:To obtain a new optical material and educational equipment for science by using a color tone-changing gel whose color is changed by external stimuli. CONSTITUTION:In the color tone-changing gel, its color is changed by external stimuli. In this case, any gel having a property of changing the color corresponding to various stimuli such as the temperature, humidity, voltage and pressure therein, or any gel to which such property is given, may be used as a gel whose color is changed by the external stimuli. Then, the high molecular gel 2 and an electrode 3 swelled in an electrolytic aq. solution in which an indicator is dissolved are arranged at the inside of an optical cell 1, a part of whose front face is transparent. When the DC voltage is applied from a power source 4, cations in the gel are diffused toward a negative electrode, thus the pH value in the vicinity of the negative electrode is increased and the color of the indicator is changed. Further, the color of the indicator is turned to the original color by reversing the positive and negative of the DC voltage.
