摘要:
A source driver supplies a grayscale voltage to a liquid crystal capacitor and a storage capacitor provided in parallel with the liquid crystal capacitor, a voltage that changes in synchronization with a polarity inversion timing being applied to one end of the storage capacitor. The source driver includes an offset value calculation section that calculates an offset value based on grayscale data corresponding to respective color components of one pixel, a grayscale data correction section that corrects the grayscale data using the offset value corresponding to the respective color components, and a source line driver section that drives a source line corresponding to the respective color components based on the grayscale data that has been corrected by the grayscale data correction section. The source line driver section drives the source line corresponding to the respective color components based on the grayscale data that has been corrected by the grayscale data correction section, and then drives the source lines corresponding to the respective color components based on the grayscale data before being corrected by the grayscale data correction section.
