Matrix address display apparatus having conductive lines and pads for repairing defects

摘要

A rescue line (18) is provided around the pixel part having display elements disposed on cross points of scanning lines (1) and signal lines (2) disposed vertically to the scanning lines (1): When one of the scanning lines (1) or the signal lines (2) is broken, the rescue line (18) is connected to both ends of the break line by the bonding pads for feeding the signal to the break line, and thereby defective function is restored.
