Problems solved by technology

Therefore, when noise due to deformation of the conductive frame 127 is formed inside the shield electrode 108 (that is, on the detection region 104 side and the wiring region 106 side), the shield electrode 108 cannot shield the noise.

Abstract

The invention relates to a touch panel and a display device comprising the same. 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.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2013-004722 filed on Jan. 15, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a touch panel for inputting information by touching the panel with a finger or the like, and a display device having the touch panel. Background technique [0004] Recently, a display device having a touch panel obtained by incorporating the touch panel into a display input device such as a ticket vending machine is being widely put into practical use. In a display device having a touch panel, buttons to be touched are displayed on the display device. When these components are pressed by a finger or the like, the fact that they are being pressed is detected and information is input. Furthermore, the display device switches images to be displayed based on the i...
