Abstract: This invention aims at reducing the probability of short-circuiting between terminals in a display device in which an IC driver is connected by COG.Terminals for connection with the IC driver are formed in a terminal region of a TFT substrate (100). The terminals are each comprised of a terminal metal (60), a first through-bole formed in a first insulation film (107), a second through-hole formed in a second insulation film (109), a first ITO (20) formed in the first through-hole and being in contact with the terminal metal (60), and a second ITO (30) formed over the first ITO (20). The second ITO (30) is formed within an area where the second ITO is in contact with the first ITO but is not formed outside the second through-hole. This ensures that the distance between the ITOs of the adjacent terminals can be enlarged, whereby the probability of short-circuiting between the terminals can be lowered.

Abstract: This invention envisages having flexible wiring substrate terminals serving to connect with the wires for preventing dielectric breakdown caused by static electricity during the manufacturing process, and reducing the number of the flexible wiring substrate terminals. On a mother TFT substrate, signal lines extend over each liquid crystal cell in a manner flanking a scribe line between the adjacent liquid crystal cells. The signal lines of each liquid crystal cell are connected with connecting lines striding the scribe line. This reduces the number of static electricity countermeasure wires extending from the flexible wiring substrate terminals of each liquid crystal cell. Once completed, the individual liquid crystal cells are separated from one another, with no adverse effects caused by the connecting lines.

Abstract: Inspection pads are reduced when there is a need to input a plurality of control signals as inspection control signals. A display device includes: an integrated circuit; a first substrate on which a plurality of signal lines that respectively input the control signals to the integrated circuit, and an inspection pad are formed; and a driver circuit that that is mounted on the first substrate and connected to the plurality of signal lines. The plurality of signal lines include first and second signal lines adjacent to each other. The inspection pad is formed on the one signal line. The second signal line is connected to the inspection pad through a switch element. At the time of inspection, the switch element turns on, and the same control signal is input to the first and second signal lines from the inspection pad.
