Abstract: In an IC mounting region in which a driver IC is to be mounted in an active matrix substrate that is used in a display device, an inspection circuit is formed together with a plurality of driving-side pads for outputting, from the driver IC, a plurality of video data signals representing an image to be displayed. The inspection circuit includes a plurality of inspection transistors connected separately to each of these driving-side pads, inspection signal lines, and an inspecting control line. The inspection signal lines and the inspecting control line are placed opposite the driving-side pads across the inspection transistors, and there are no wire intersections between the inspection transistors and the driving-side pads.

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.
