Abstract: A touch panel includes a first portion extending in a first direction within a pixel region, a source driving circuit, an inspection circuit, an input terminal region, and an inspection line extending in the first direction within a frame region. The inspection line is formed in a layer different from a layer where the first portion is formed. The inspection line is connected to the first portion and a second portion via a contact hole between a touch-detecting electrode and the source driving circuit. The second portion crosses the source driving circuit and the inspection circuit in a direction intersecting the first direction.
