According to one embodiment, a display device comprises an insulating substrate, a pixel in a display area, a scanning line extending in a first direction, a signal line extending in a second direction, a shield line between the insulating substrate and the scanning line, a pixel electrode in the pixel, and a first switching element including a first semiconductor layer. The first semiconductor layer is provided between the scanning line and the shield line, and comprises an intersection area in which the first semiconductor layer intersects the scanning line. The shield line overlaps the intersection area, and is electrically connected to the scanning line through a contact portion.
