1. A display device equipped with a touch panel, the display device comprising:

  • a device chassis provided with an opening section;

    a planar display panel including an upper polarization plate, an upper glass plate, a liquid crystal layer, a lower glass plate, and a lower polarization plate and having a display surface disposed accessible through the opening section and formed of a surface of the upper polarization plate, the upper and lower polarization plates being smaller than the upper and lower glass plates;

    a continuous surface sheet for covering the touch panel on the opposite side to the display panel, and closing the opening section to form a substantially the same surface with the device chassis,wherein the touch panel is provided with an expanded section protruding laterally from an outer edge of the display panel, the expanded section is provided with one or more input sections each having a corresponding operation switch, anda reinforcing area for improving resistance against pressing force applied from the outside is provided in a predetermined portion of the surface sheet, the reinforcing area includes one or more operating areas that are disposed atop the one or more input sections, and the continuous surface sheet coincides with the reinforcing area and is distortable at the one or more input sections for operating the corresponding operation switch;

    a support member affixed to an inside part of the device chassis and including a base section for supporting the display panel and a plurality of holding members formed continuously with and disposed along at least two edges of the base section and configured to secure the display panel;

    a planar light source means for supplying the display panel with light and having a substantially same area as the display panel, the light source means being disposed between the support member and the display panel and being secured by the holding members of the support member;

    a first inner frame member for framing an inner surface and part of a side surface of the display panel;

    a first outer frame member for framing an outer surface and another part of a side surface of the display panel, an outer edge of the first inner frame member and an outer edge of the first outer frame member engaging each other along the side surface of the display panel;

    a first flexible wiring board electrically connected to the display panel and extending through a through hole formed of a notch formed in the outer edge of the first inner frame member and a notch formed in the outer edge of the first inner frame member;

    a second inner frame member for framing an inner surface and part of a side surface of the light source means;

    a second outer frame member for framing an outer surface and another part of a side surface of the light source means, an outer edge of the second inner frame member and an outer edge of the second outer frame member engaging each other along the side surface of the light source means; and

    a second flexible wiring board electrically connected to the light source means and extending through a through hole formed of a notch formed in the outer edge of the second inner frame member and a notch formed in the outer edge of the second outer frame member.
