Claim 2:
3. The display driver according to claim 1, further comprising:
a control part which generates an image data signal including a series of display data pieces representing the brightness level of each pixel based on the image signal, receives an input operation for setting a state of the test polarity inversion signal to a logic level 0 or a logic level 1, and inserts the test polarity inversion signal set by the input operation into the image data signal;
a data latch part which captures the series of the display data pieces included in the image data signal and supplies each of n display data pieces as the first to n-th display data pieces to the conversion part at each time of capturing; and
a polarity inversion signal extraction circuit which extracts the test polarity inversion signal from the image data signal and supplies the test polarity inversion signal to the first selector.
