Abstract: This invention envisages 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: 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 translation: 本发明设想具有用于连接导线的柔性布线基板端子，用于防止在制造过程中由静电引起的电介质击穿，并且减少柔性布线基板端子的数量。 在母TFT基板上，信号线以相邻的液晶单元之间的划线侧面的方式在每个液晶单元上延伸。 每个液晶单元的信号线与跨越划线的连接线连接。 这就减少了从每个液晶单元的柔性布线基板端子延伸的静电对抗线的数量。 一旦完成，各个液晶单元彼此分离，没有由连接线引起的不利影响。
