Abstract: Disclosed is a display device having a first layer and a second layer over the second layer. The first layer possesses a display region including: a plurality of first sub-pixels; a plurality of second sub-pixels; a plurality of third sub-pixels; a partition wall sandwiched by two adjacent sub-pixels; and a sealing film thereover. The second layer includes: a first touch electrode overlapping with the partition wall and arranged along the partition wall; and a second touch electrode overlapping with the partition wall, arranged along the partition wall, and intersecting the first touch electrode. The first touch electrode and the second touch electrode exist in the same layer. The first touch electrode and the second touch electrode each have a plurality of openings. Among the number of the first sub-pixels, the number of the second sub-pixels, and the number of the third sub-pixels, one is different from the other two.

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: The first and second touch electrodes constitute a mesh shape of staying away from overlap with the light-emitting pixels. Each electrode body has a first slim portion between adjacent light-emitting pixels in the first direction. Each electrode body has a first wide portion between adjacent light-emitting pixels in the second direction. The first wide portion is wider than the first slim portion. The jumper electrode has a second slim portion between adjacent light-emitting pixels in the first direction. The jumper electrode has a second wide portion between adjacent light-emitting pixels in the second direction. The second wide portion is wider than the second slim portion. The light-emitting pixels each have a planar shape longer in the second direction than in the first direction. The first and second wide portions are overlapped and electrically conductive, penetrating the insulation film.

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.
