Abstract
A display circuit for a simple matrix type liquid crystal display apparatus which is multiduty. The picture element data of one line portion is sequentially output through the segment driver into one electrode contacting the liquid crystal. The scanning pulses are sequentially output through the command driver into the other electrode contacting the liquid crystal. The driving circuit further reverses the polarities of the outputs at a constant period with an alternating signal, so as to drive the respective liquid crystal.
