<p>PROBLEM TO BE SOLVED: To unnecessitate a spacer member and to obtain excellent display quality without moire fringes by air-tightly sticking the four sides of a film and a glass plate and enclosing pressure gas which is slightly larger than atmospheric pressure between the film and the glass plate. SOLUTION: An input device 10 is composed of a film 11 and a glass plate 12 made of transparent and flexible material. Between the four sides except the touch surface 13 of the film and the glass plate 12, a sticking part 14 shown by the hutching on a figure is provided. The sticking part 14 is tightly jointed by adhesive so that air may not be entered and the space of a prescribed height is formed between the touch surface 13 and the glass plate 12. In the film 11 to be the part of the touch surface 13, that is, the film covering this space, the tension of a proper size is imparted along the surface direction. Gas is enclosured in this space and the pressure of this gas is set to the degree which is slightly lager than the atmospheric pressure (the average pressure of main cities is desirable).</p> |
