  • Publication number: 20080018849
    Abstract: A right end portion of a power supply wiring located at the right end side of a bus wiring portion FPC, and a left end portion of a power supply bus wiring located at the left side of an interface portion FPC which is spaced from the right side of the bus wiring portion FPC so as to face the right side concerned are electrically connected to each other by an in-glass connecting bus wiring provided onto one principal surface of a mount portion of a glass substrate. A substrate portion can be divided into two FPCs, positioning can be facilitated, a press-fitting frequency can be reduced and the number of manufacturing steps can be reduced. The shapes of FPCs can be set to a simple shape such as a rectangular shape or the like, so that the number of FPCs which can be yielded can be enhanced, and the product cost can be suppressed.
