Level shifter, shift register with level shifter, and display device with shift register

Abstract

In one embodiment of the present invention, a NAND circuit, an inverter, a plurality of transistors serve as stopping devices for stopping operation of a circuit in a manner responsive to a level of an initializing signal that is fed. If the initializing signal that is Low-level is fed into the NAND circuit, then a plurality of transistors all become OFF. This makes it possible to reduce steady current flowing across a voltage and a start signal. Steady current flowing across the voltage and a start inverted signal is also reduced. Thus, the steady current flowing through the level shifter is reduced reliably, regardless of the way of use, when necessary.
