Abstract
A shift register has four systems of shift registers for bidirectional scans and normal/redundant lines. The respective systems of shift registers are divided into blocks, so that transmission circuits are provided therebetween. The transmission circuits form switching circuits through transfer gates. The transmission circuits receive output signals from both of the shift registers for the normal/redundant lines, and output only normal output signals to next stage shift registers in accordance with control signals.
