Display device having touch panel
First Claim
1. A display device having a touch panel comprising:
- a display panel;
a capacitance-type touch panel arranged on the display panel; and
a front panel arranged on the capacitance-type touch panel;
wherein the capacitance-type touch panel includes a plurality of X-electrodes and Y-electrodes;
wherein the capacitance-type touch panel and the front panel are attached to each other at peripheral portions of the capacitance-type touch panel using adhesives;
wherein a conductive film that is provided so as to surround an effective touch area of the capacitance-type touch panel is provided on the uppermost layer of the capacitance-type touch panel;
wherein predetermined electric potential is supplied to the conductive film;
wherein the conductive film overlaps peripheral portions of the effective touch area of the capacitance-type touch panel in planar view; and
wherein end portions of the conductive film where the peripheral portions of the effective touch area of the capacitance-type touch panel overlap are positioned within a range of 3 mm to 5 mm of the peripheral portions of the effective touch area of the capacitance-type touch panel in planar view.
