Abstract: The display device includes a substrate, a pixel, an image-signal line, a counter substrate over the pixel and the image-signal line, a touch-detecting electrode, and a first terminal portion. The pixel is located over the array substrate and includes a pixel electrode, a common electrode, and a liquid crystal layer. The image-signal line is located over the substrate and is electrically connected to the pixel. The touch-detecting electrode is located over the counter substrate and extends in a direction intersecting with a direction in which the common electrode extends. The first terminal portion is electrically connected to the touch-detecting electrode. The first terminal portion is spaced from a first edge of the counter substrate intersecting with the image-signal line. A plane shape of the first terminal portion in a plane parallel to a surface of the counter substrate has at least one first curved portion facing the first edge.

Abstract: The display device includes a detection electrode, a display pattern, a detection circuit connected to the detection electrode, a plurality of subpixel regions in which pixel electrodes are formed, pixel regions each composed of the subpixel regions, and a display region in which the pixel regions are arrayed. The pixel regions each include a first color subpixel region and a second color subpixel region. The subpixel regions are arrayed in a Y direction in the display region. First patterns having a circular or polygonal shape in a plan view are formed in the detection electrode. The detection electrode includes a first region electrically connected to the detection circuit and a second region separated from the detection circuit inside the display region. The first region extends in an X direction and a virtual line connecting centers of the adjacent first patterns extends in the X direction.
