ABSTRACT:
A driving circuit for the display apparatus having a plurality of output terminals includes a couple of selecting parts for selecting either a potential VDD2 or a potential VDD4 by control signals 221S, 222S, 231S and 2342S and then outputting said selected potentials as V1 and V2, respectively; and a plurality of output parts: say, one of the odd numbered output parts 202 having, in common with other odd numbered output parts, potentials VDD1 and VDD3 and said selected potential V1, and selecting one potential out of them by control signal 241S, 242S and 243S and outputting said selected next potential as a driving signal; one of the even numbered output parts 203 having, in common with other even numbered output parts, said potentials VDD1 and VDD3 and said selected potential V2, and selecting one potential out of them by control signal 251S, 252S, 253S and outputting said selected next potential as a driving signal.
