Claim 15:
16. The display device according to claim 15,
wherein the source driver includes:
an interface unit which receives the video data signal and acquires the plurality of pixel data pieces from the video data signal received,
a plurality of latch units which is provided to correspond to the plurality of source lines and latches and outputs the pixel data piece from the interface unit, and
a plurality of gradation voltage generation units which is provided to correspond to the plurality of source lines, includes the first gradation voltage generation unit and the second gradation voltage generation unit, and respectively generates a gradation voltage based on the pixel data piece output from the plurality of latch units,
wherein the interface unit is operated in one of a first operation mode and a second operation mode, supplies a pixel data piece corresponding to the video data signal to the plurality of latch units in the first operation mode, and supplies a pixel data piece corresponding to a first color display to the plurality of latch units regardless of the video data signal in the second operation mode, and
wherein when the interface unit is operated in the second operation mode and the comparison result of the voltage comparison unit shows a predetermined result, the data writing unit supplies a pixel data piece corresponding to a second color display different from the first color display to the latch units corresponding to the third source line and the fourth source line.
