Abstract
A source driver includes a data latch unit that outputs acquired pixel data, a gradation voltage conversion unit that acquires the pixel data outputted from the data latch unit and converts the pixel data to gradation voltages, an output unit that amplifies and outputs the gradation voltages to source lines, and a timing control unit that controls the timing of the output of the pixel data from the data latch unit. The timing control unit performs control such that the longer a source line is from a source driver to a pixel column, the smaller the timing difference is between acquisition of the pixel data by the data latch unit and the output of the pixel data.
