Abstract:
1. A display comprising a shift register circuit including: a first circuit section having a first transistor of first conductive type connected to a first potential and operated to turn on in response to a clock signal, a second transistor of first conductive type connected to a second potential, and a third transistor of first conductive type connected between the gate of said first transistor and said second potential and operated to turn off said first transistor when said second transistor is in on state; and a second circuit section having a fourth transistor of first conductive type connected to said first potential and operated to turn on in response to said clock signal, a fifth transistor of first conductive type connected to said second potential, and a sixth transistor of first conductive type connected between the gate of said fourth transistor and said second potential and operated to turn off when said third transistor is in on state, said sixth transistor being operated to turn off said fourth transistor when said fifth transistor is in on state; an output positioned between the first and second transistors of the first circuit section being connected to gates of the fifth and sixth transistors of the second circuit section.
