Abstract
In an LCD, there is used a GH-mode liquid crystal of which change in transmittivity due to variation in gap thickness is less than that of the conventional TN liquid crystal. A tablet facility is directly arranged or electrodes having the function of the tablet are formed over or below the liquid crystal. Thanks to the structure, this protection plate conventionally required to prevent the change in gap thickness resulting due to pressure of a pen input device applied to the LCD can be eliminated. Consequently, it is possible to reduce weight, volume, and parallax of the LCD. An active matrix LCD with integrated table-type input device is attainable in a simple configuration without increasing weight and volume thereof.
