1. A switching circuit, comprising:
a first switching element;
a second switching element which is electrically connected to the first switching element; and
a voltage maintaining unit which maintains a first voltage difference between a gate region and a source region of the first switching element to be constant, maintains a second voltage difference between a gate region and a source region of the second switching element to be constant, and maintains the first voltage difference and the second voltage difference to be the same.
