<P>PROBLEM TO BE SOLVED: To reduce a drive voltage of a driver circuit to attain low power consumption of the driver circuit. <P>SOLUTION: The amplitude voltage of a signal IN1 can be increased and then output by a level shifter circuit. Specifically, the amplitude voltage of the signal IN1 can be increased and output. This decreases the amplitude voltage of a circuit (a shift register circuit, a decoder circuit, or the like) which outputs the signal IN1. Consequently, power consumption of the circuit can be reduced. Alternatively, a voltage applied to a transistor included in the circuit can be reduced. This can suppress degradation of the transistor or damage to the transistor. <P>COPYRIGHT: (C)2011,JPO&INPIT |
