Patent ID: 7027043

Claim:
A wiring substrate connected structure for facilitating repairs in a display, comprising: a substrate connected structure for connecting two wiring substrates in such a manner that a plurality of connection wirings formed on respective wiring substrates are electrically connected in a substrate connection part so that the plurality of connection wirings are provided on both of the two wiring substrates so that respective ones of the connection wires on a first of the wiring substrates are electrically connected to corresponding ones of the connection wires on a second of the wiring substrates, wherein: each of said wiring substrates comprises at least one auxiliary wiring formed so as to cross said plurality of connection wirings formed on each of said wiring substrates via an insulating film, wherein the auxiliary wirings on the two wiring substrates are electrically connected to each other; and wherein the auxiliary wiring and the connection wirings on the first wiring substrate overlap each other on the first wiring substrate and the auxiliary wiring and the connection wirings on the second wiring substrate overlap each other on the second wiring substrate so as to facilitate an electrical connection between one of the connection wirings and both of the auxiliary wirings upon detection of a defect in the one connection wiring in an area outside of a display area and between the auxiliary wirings.
