<p>PURPOSE:To eliminate parallax between the abutting position of the tip of an input pen or the finger and an image display panel and to simplify configuration by forming an image, which is displayed at a display device, in a diffused layer by using an image forming means composed of a lens array. CONSTITUTION:On a liquid crystal display device 4, the lens array parallelly joining a lot of refractive index distribution lenses is provided as an image forming means 5 and on that means 5, a position input means 6 forming a transparent electrode 62 composed of ITO on a transparent board 61 is provided. A diffused layer 7 is formed on the transparent board 61 of the position input means 6 by the thin film of light diffusing resin applied to cover the transparent electrode 62, provided with a function as a transmissive screen to form unmagnified erect normal images and simultaneously provided with a function as the protection film of the transparent electrode 62. The transparent electrode 62 provided at the position input means 6 is connected through a signal generation detector 63 provided with an oscillation circuit or the like to a controller 9, and position information is inputted to the controller 9 by abutting an input pen 3 to the diffused layer 7.</p> |
