Abstract
A collective substrate of active-matrix substrates is divided into a first block and a second block. In cells of the first block and the second block, from a corresponding signal input pad group, an inspection scanning signal is inputted via a scanning-line short ring connecting line to scanning lines, an inspection display signal is inputted via a signal-line short ring connecting line to signal lines, and an auxiliary capacity wire signal is inputted via an auxiliary capacity wire main wire connecting line to auxiliary capacity wires. This arrangement makes it possible to perform an electrical inspection with high accuracy and efficiency on a large-format active-matrix substrate, and to manufacture an inspection probe frame in a simple manner at low cost.
