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.
