ABSTRACT:
A driver for a liquid crystal device includes a plurality of common drivers having a first common driver and a last common driver for comb-like driving that is coupled in cascade connection and a frequency divider that produces a second clock for interlaced driving by halving a period of a first clock that is provided from outside for serving as a basis of driving the drivers regarding each of the common drivers for comb-like driving aside from the first common driver and the last common driver. A converter circuit converts two periods of output data that are output in response to input data corresponding to one period of the first clock into one period of output data by using the second clock regarding input and output data of each of the common drivers for comb-like driving.
