ABSTRACT:
A driving circuit in a matrix type image display apparatus including a plurality of groups each including four standard unit circuits and one backup unit circuit. Each standard unit circuit includes disconnecting means for isolating the standard unit circuit from the driving circuit, and the backup unit circuit includes connecting means for connecting the backup unit circuit to an input signal line and an output signal line of any of the standard unit circuits within a group. The number of the backup unit circuits can be changed in accordance with a conforming ratio of each unit circuit, which makes it possible to eliminate idle backup unit circuits while maintaining a high overall conforming ratio of the driving circuit, thereby enhancing manufacturing efficiencies and reducing manufacturing costs.
