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: A display device includes lead lines that extend from a display area, and electrically connect video signal lines or scanning signal lines within a display area, and a driver circuit or a terminal portion that receives an output from the driver circuit; an insulating film that is formed in an upper layer of the lead lines and covers the lead lines; and a conductive film that is formed in an upper layer of the insulating film. The lead lines include a plurality of first lead lines that start from the driver circuit or the terminal portion, and arrive at the scanning signal lines or the video signal lines, and a plurality of second lead lines that are smaller in wiring resistance than the first lead lines. At least the first lead lines overlap with the conductive film through the insulating film.

Abstract: A black matrix is formed to an edge of a counter substrate. Then, a BM slit, which is an area where the black matrix is not present, is formed in the periphery of a seal material in order to prevent water or moisture from penetrating from the interface between the counter substrate and the black matrix. Then, a light shielding metal is formed in a layer other than a lead line layer, on the side of a TFT substrate, in order to prevent light from leaking from the BM slit. With this structure, it is possible to prevent the light from leaking from the BM slit around a screen. As a result, the degradation of the contrast can be prevented in the periphery of the screen.

Abstract: A display device is configured to provide a crack detection line running from a first crack detection terminal along a side of a TFT substrate to extend to a second crack detection terminal. A switching transistor for switching between an image display and crack detection is provided at a side opposite a terminal portion between the crack detection line and a video signal line. The crack that may cause disconnection in the crack detection line is detected by turning the switching transistor on, and applying the voltage for lighting inspection to the first crack detection terminal and the second crack detection terminal sequentially in this order.
