1. A liquid crystal display device includinga liquid crystal panel havinga first substrate,a second substrate facing said first substrate,a liquid crystal layer disposed between said first substrate and said second substrate, andfirst and second electrodes formed on a surface side, of said first substrate, facing said second substrate,a transverse electric field being applied to said liquid crystal layer through said first and second electrodes, thereby displaying an image in a pixel area;

  • wherein said first substrate comprises;

    a light receiving element provided on the surface, of said first substrate, facing said second substrate, for receiving an incident light made incident from a side of said second substrate to a side of said first substrate through said liquid crystal layer on a light receiving surface thereof, thereby forming data on the received light; and

    a planarizing film provided on the surface side, of said first substrate, facing said second substrate so as to cover said light receiving element;

    said first and second electrodes are provided on said planarizing film in said pixel area, an insulating film being interposed between said first and second electrodes; and

    said insulating film is provided in an area corresponding to a sensor area having said light receiving element provided therein on a surface of said planarizing film.
