First Claim
1. A stage, comprising:
- an output to supply a voltage of a first power source or a second power source to an output terminal based on voltages of a first node and a second node;
an input to control voltages of a third node and a fourth node based on signals supplied to a first input terminal and a second input terminal;
a first signal processor to control the voltage of the first node based on the voltage of the second node;
a second signal processor, connected to a fifth node, to control the voltage of the first node based on a signal supplied to a third input terminal;
a third signal processor to control the voltage of the fourth node based on the voltage of the third node and the signal supplied to the third input terminal; and
a first stabilizer connected between the second signal processor and the input to control voltage drop widths of the third node and the fourth node.

Abstract
A stage includes an output, an input, signal processors, and a stabilizer. The output supplies a voltage of a first or second power source to an output terminal based on voltages of first and second nodes. The input controls voltages of third and fourth nodes based on signals to a first and second input terminals. A first signal processor controls the voltage of the first node based on the voltage of the second node. A second signal processor is connected to a fifth node and controls the voltage of the first node based on a signal to a third input terminal. A third signal processor controls the voltage of the fourth node based on the voltage of the third node and the signal to the third input terminal. The stabilizer is connected between the second signal processor and input to control voltage drop widths of the third and fourth nodes.
