  • Publication number: 20140158401
    Abstract: The present invention provides a display panel and a wiring structure thereof. The wiring structure comprises a plurality of metal wires extending across a first wiring region, a second wiring region, and a third wiring region. The first wiring region adjoins the second wiring region. The second wiring region adjoins the third wiring region. A line width of an nth metal wire in the second wiring region is a, and a distance between the nth metal wire and an n+1th metal wire is b, where n?1. When n is taken as different values, a/(a+b) is a constant value. According to the above method, the coverage ratio in the seal coating region by the metal wires is not changed to avoid the problem of uneven curing of the sealant. The performance stability of the display panel is thus not impacted.
