ABSTRACT:
In a driving circuit for a liquid crystal apparatus, a DC offset voltage the level of which changes depending upon the level of input video signals is applied as an input video signal. The DC voltage which appears in the liquid crystal and the level of which changes depending upon the level of input video signals can be completely compensated.
