A driving circuit for a matrix type liquid crystal display device is disclosed. The driving circuit comprises: a gate driver for, during a writing period, selectively driving a scanning line included in a group of scanning lines which correspond to the field to be scanned, and for, during an erasing period, selectively driving a scanning line included in another group of scanning lines which do not correspond to the field to be scanned; a source driver for, during said writing period of an even field, applying a signal voltage the level of which corresponds to a video signal, to the signal lines, and for, during the erasing period, applying a voltage to the signal lines to set the voltage applied to the picture elements to a level below the threshold level of the picture elements; and another source driver for, during said writing period of an odd field, applying a signal voltage the level of which corresponds to a video signal, to the signal lines, and for, during the erasing period, applying a voltage to the signal lines to set the voltage applied to the picture elements to a level below the threshold level of the picture elements. The writing period and the erasing period shares one horizontal scanning period.
