<p>PURPOSE:To make a keyboard small-sized by providing the keyboard made of a transparent pressurized conductive elastic material on a liquid crystal display device. CONSTITUTION:The size of the upper surface of a liquid crystal display device 2 provided on a frame 1 is nearly equal to the size of the upper surface of the frame 1. A keyboard 3 made of a transparent pressurized elastic material is provided on the display device 2. The area of the upper surface of the frame 1 can be thereby decreased by the area of the upper surface of the keyboard 3. The produced document is displayed on the display device 2, and the display content can be observed through the keyboard 3.</p> |
