  • Patent number: 8054436
    Abstract: A substrate for display device is provided. As a wiring structure of the substrate, the scan line layer and the signal line layer are not connected directly by arranging through-holes between the scan line layer and the signal line layer, but are connected through an ITO layer by arranging through-holes between the scan line layer and the ITO layer and arranging through-holes between the signal line layer and the ITO layer, with an object to reduce the value of the connection resistance between the scan line layer and the signal line layer. Through-holes connecting the scan line layer and the ITO layer and through-holes connecting the signal line layer and the ITO layer are configured in a comb shape respectively and engaged with each other. Thus the length of the ITO connecting the scan line layer and the signal line layer becomes shorter and the value of the connection resistance is reduced.

  • Patent number: 7602453
    Abstract: A liquid crystal display (LCD) device has a wiring structure of superfine wiring, wherein it can reduce the occurrence rate of electrostatic discharge (ESD), and the time constant of the scan line can be improved simultaneously. The wiring width in the portions of the scan lines where they intersect the auxiliary capacitance bunching lines is narrowed, so that the area of the intersection and the wiring capacitance is reduced, thus the time constant of the scan line is decreased, meanwhile, the wiring width in portions of the auxiliary capacitance lines where they intersect the auxiliary capacitance bunching line is enlarged, the distance between the adjacent scan line and the nearest portion of the auxiliary capacitance line is shortened, and the ESD occurs at the nearest portion, and the failure products caused by the ESD can be decreased.
