The shift register comprises: a signal outputting circuit (32), a signal inputting circuit (31), an inverting circuit (33) and a logic circuit (33).

The inverting circuit (33) receives an inverse direction clock signal from the external circuit, turns off the clock transistor and turns on the level transistor at the same time when the inverse direction clock signal is valid. The logic circuit (33) holds the clock transistor as being turned on before the level transistor is turned on.
