Abstract
A shift register is formed by connecting unit circuitsin multi-stage. One electrode of a capacitor Capin the unit circuitis connected to the gate terminal (node N) of a transistor T, and the other connected to a node N. A compensation circuit composed of transistors Tto Tprovides a clock signal CKB to the node Nwhen the node Npotential is at low level, and applies a low-level potential to the node Nwhen the node Npotential is at high level. Accordingly, even when the gate potential of the transistor Tchanges with a change in a clock signal CK, a signal that cancels out the change is provided through the capacitor Cap, stabilizing the gate potential of the transistor T. Thus, a change in the control terminal potential of an output transistor associated with a change in a clock signal is prevented.
