Abstract
In a touch panel incorporating a display device, a first sensor line (120) narrower than a first dummy line (130) is disposed on an interlayer insulating film (240) formed on an insulating substrate (100) at a location corresponding to a first dummy line (130), and a second sensor line (150) narrower than the data line (140) is formed on the interlayer insulating film (240) at the location corresponding to the data line (140). The first sensor line (120) and the second sensor line (150) are disposed such that they do not extend beyond the widths of the first dummy line (130) and the data line (140), respectively, when observed in a plan view. Provided is a touch panel incorporating a display device in which the locations of the first sensor line (120) and the second sensor line (150) are adjusted to prevent the aperture ratio reduction in the display element section (11).
