Abstract: Provided is a display device which has a rectangular display region with four sides. The display region includes a gate line, a signal line, a first sub-pixel electrically connected to the gate line and the signal line, and a light-emitting element included in the first sub-pixel. The gate line includes a first linear portion and a second linear portion which have vectors different in direction from each other, and the first linear portion and the second linear portion are directly connected to each other. The signal line includes a third linear portion and a fourth linear portion which have vectors different in direction from each other, and the third linear portion and the fourth linear portion are directly connected. The first to fourth linear portions are each inclined from the four sides.

Abstract: A display device includes: a first organic layer; display elements over the first organic layer in correspondence with the pixels; an inorganic layer sealing the display elements and the first organic layer; a second organic layer on a part of the inorganic layer; and a touch electrode on a surface of the inorganic layer and a surface of the second organic layer. The first organic layer has a rift in the peripheral area to surround the display area. The inorganic layer includes a concave part over the rift, and extends from the display area to the peripheral area continuously. The second organic layer is on the concave part of the inorganic layer. The surface of the second organic layer on which a touch electrode is put is contiguous to and is surrounded by the surface of the inorganic layer on the concave part.

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.
