Abstract
A redundant wiring apparatus used for a liquid crystal display apparatus and a method of a making the same are disclosed. The liquid crystal display device includes a switching circuit array substrate and a counter substrate provided opposite to the array substrate. Signal and scanning lines are disposed on the array substrate in a matrix form. The signal and scanning lines are connected pixel electrodes through the switching circuits formed on the array substrate. A display region and a surrounding region are provided on the array substrate. The signal and scanning lines have lead wires extending from the display region to the surrounding region. The lead wires are redundant in wiring structure in which a first wire, an insulation layer and a second wire are laminated. The first and second wires are electrically connected through connectors received in through-holes at both ends of the first wire. Repair portions of the first and second wires are provided in the vicinity of through-holes. The repair portions are not overlapped with each other for the convenience of repair. When the first or/and second wires of neighboring lead wires are sort-circuited, the repair portions of the first and second wires are cut off to repair by irradiating laser beams.
