Abstract: A sealing member containing conductive particles and disposed in a seal region is formed between a display panel and a touch panel. A laminated structure formed on the display panel includes a first detection lines. The first detection lines extend from the seal region to a connection region and are connected through the conductive particles to terminals of second detection lines formed on the touch panel. A peripheral edge of the organic barrier is located inward from the conductive particles of the sealing member. The above described structure can facilitate a work for connecting external lines such as FPC to the display panel and the touch panel. Further, the structure can secure stability of electrical connection between the external lines and the touch panel.

Abstract: First electrodes are formed on an insulation surface in such a manner that the adjacent first electrodes are connected in a first direction and are separated in a second direction intersecting the first direction. Second electrodes are formed on an insulation surface in such a manner that the adjacent second electrodes are connected in the second direction and are separated in the first direction. Third electrodes are formed in regions in which the third electrodes overlap with the first electrodes and do not overlap with the second electrodes in such a manner that the adjacent third electrodes are connected in the second direction and are separated in the first direction. A flexible insulation layer is formed between the first electrodes and the third electrodes. An area of each of the third electrodes is less than an area of each of the first electrodes.
