Touch panel and display device comprising the same
First Claim
1. A display device including a touch panel, the touch panel comprising:
- a substrate;
a detection region formed on the substrate, for generating a detection signal according to a contact position of a conductor;
a plurality of detection electrodes formed on the substrate outside the detection region, for outputting the detection signal generated in the detection region;
a transparent conductive frame above an outer perimeter of the detection region on the substrate; and
a transparent shield electrode formed on a same surface on the touch panel as the detection region, on the outer perimeter of the detection region and between each of the plurality of detection electrodes,wherein a distance from the detection region to the shield electrode is shorter than a distance from the detection region to the transparent conductive frame.

Abstract
To shield the noise generated due to deformation or the like of the conductive frame. The touch panel includes: a detection region which generates detection signals according to a contact position of a conductor; a plurality of detection electrodes which output detection signals generated in the detection region; a conductive frame which covers above the outer side of the detection region and above the detection electrode; and shield electrodes formed on the outer side of the detection region on the CF substrate and between each of the plurality of detection electrodes, to which shield signals for shielding the electric influence on the detection region and the detection electrodes are supplied. Further, the distance between the shield electrodes and the detection region is shorter than distance between the conductive frame and the detection region.
