Abstract
A liquid crystal display device has a position information input device over an image-displaying surface of liquid crystal panel. The position information input device is formed by a first substrate and a second substrate more easily deformable than the first substrate. A transparent insulation film is provided over a surface of the first substrate opposed to the second substrate. By providing a first transparent electrode on the transparent insulation film, the flatness of the first transparent electrode is improved and a connection failure of the position information input device is prevented.
