ABSTRACT:
A display drive circuit including a pulse generator means; a variable voltage source circuit including a first voltage source line (VD.sub.t) with a variable potential, a second voltage source line (VS.sub.t) with a potential different from the first voltage source line by a constant value, having a voltage waveform, a variation period and a variation component the same as the first voltage source line, and varying in potential with a potential level not more than the lowest potential level of the first voltage source line, and other voltage source lines with constant potential levels between the potentials of the first and second voltage source lines; and an integrated circuit having an electronic switch which switches at a constant period the connection of the voltage source lines so as to make a plurality of constant waveform voltages, outputting these to a plurality of output terminals at constant phase difference.
