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.

A display device comprising:
- a display panel including a display region;
- a touch panel facing the display panel;
- a seal region located outside the display region and surrounding the display region;
- and
- a connection region located outside a portion of a peripheral edge of the seal region, wherein
- the display panel includes a first substrate and a first laminated structure formed on a surface of the first substrate facing the touch panel,
- the touch panel includes a second substrate and a second laminated structure formed on a surface of the second substrate facing the display panel,
- the first laminated structure includes:
- an organic layer including a light emitting layer and formed on the display region;
- and
- a multilayer barrier covering the whole of the organic layer and including a first inorganic barrier layer that includes an inorganic material, an organic barrier layer that includes an organic material and is formed on the first inorganic barrier layer, and a second inorganic barrier layer that includes an inorganic material and covers the whole of the organic barrier layer,
- the second laminated structure includes a circuit layer including a detection electrode and a second detection line that extends from the detection electrode and includes a terminal in the seal region,
- a sealing member is located in the seal region and disposed between the display panel and the touch panel, the sealing member containing a conductive particle,
