A liquid-crystal shutter driving circuit comprises a power supply (10) for generating multiple voltages, a field detector (20) for detecting even or odd field signals in the synthesized image signal, a LC driving frequency generator (30) for generating the characteristic and different-phase driving frequency, a field driving frequency generator (40) for generating the even or odd field driving frequency when even or odd sield signals correspond to the level of LC driving frequency, first and second stage buffers (50,60), and left/right LC shutter drivers (70,80) for driving the left/right liquid crystals.
