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.
