Abstract: The general field of the invention is that of flat-screen display devices comprising a touch surface. Such a device comprises a conductive mechanical holder in which are housed: on the bottom of the holder, a display panel comprising, on its upper face, a transparent electrical shielding film of dimensions substantially identical to those of the matrix panel; and a touch panel of dimensions substantially identical to those of the display panel, said touch panel being located above said display panel, its lower face being placed just above the shielding film. The display device according to the invention comprises a flexible conductive film that forms the ground path between the electrical shielding film and the bottom of the conductive mechanical holder, the conductive film and the shielding film making contact on the periphery of the display panel.
