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: 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.
