To provide a thin and light liquid crystal display device high in light transmittance by fabricating a liquid crystal panel, a touch panel and a backlight as a piece of constituting component and reducing the number of panel sheets causing thickening, increase in weight and light quantity lowering.

This device is constituted so that a transparent electrode layer 205 formed on the panel substrate of the touch panel 200 is formed directly on the surface of the surface panel substrate 110 of the liquid crystal panel 100, and the flexible sheets 210 of the touch panel 200 are laminated/arranged on the surface panel substrate 110 of the liquid crystal panel 100 through spacers 206, and the surface panel substrate 110 of the liquid crystal panel 100 is sharedly used as the panel substrate of the touch panel 200. Thus, since the surface panel substrate 110 of the liquid crystal panel 100 is sharedly used as the panel substrate of the touch panel 200, the thickness and the weight of the part overlapping the liquid crystal panel 100 on the touch panel 200 are made thinner and lightened.
