Touch panel and liquid crystal display device having the touch panel

摘要

A touch panel includes plural scanning electrodes, plural detection electrodes that are formed to intersect with the plural scanning electrodes, one or a plurality of layers being disposed between the plural detection electrodes and the plural scanning electrodes, plural holes that are arrayed apart from each other on each of the plural detection electrodes, and shaped into polygons each shaped to have five or more corners in a plan view, and plural dummy electrodes that are formed between the respective adjacent detection electrodes, made of the same material as that of the detection electrode, and electrically isolated from each other, in which the plural dummy electrodes are shaped into the polygons in a plan view.

1. A touch panel, comprising:
a plurality of scanning electrodes; a plurality of detection electrodes that are formed to intersect with the plurality of scanning electrodes, one or a plurality of layers being disposed between the plurality of detection electrodes and the plurality of scanning electrodes; a plurality of holes that are arrayed apart from each other on each of the plurality of detection electrodes, and shaped into polygons each shaped to have five or more corners in a plan view; and a plurality of dummy electrodes that are formed between the respective adjacent detection electrodes, made of the same material as that of the detection electrode, and arrayed apart from each other, wherein a surface shape of the plurality of dummy electrodes have the same polygonal shape as that of the hole of the detection electrodes, and the surface shape of the plurality of dummy electrodes are not the same as that of the detection electrodes.
