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 signal obtained through sampling a gate start pulse signal GSP by using one of a plurality of gate clock signals is supplied as a shift pulse for a forward shift action (a forward shift start pulse signal) to the first stage of a plurality of stages constituting a bidirectional shift register, and a signal obtained through sampling the gate start pulse signal GSP by using another one of the plurality of gate clock signals is supplied as a shift pulse for a backward shift action (a backward shift start pulse signal) to the last stage of the plurality of stages constituting the bidirectional shift register.
