Abstract
A data driver includes a capture start timing setting register in which is set data for setting capture start timing of the gray-scale data based on a signal which indicates supply start timing of the gray-scale data, and a capture instruction signal generation circuit which generates first and second capture instruction signals which are delayed in relation to the signal which indicates the supply start timing of the gray-scale data for a period corresponding to the data set in the capture start timing setting register. First and second data latches capture gray-scale data on a gray-scale bus at timing based on the first and second capture instruction signals, respectively. First and second driver circuits drive comb-tooth distributed data lines belonging to first and second groups based on the gray-scale data captured in the first and second data latches, respectively.
