Display driving device and display apparatus comprising the same

A display apparatus which displays image information based on a video signal, on a display panel having a plurality of display pixels arranged in a matrix manner adjacent to intersections of a plurality of signal lines and a plurality of scanning lines, the display apparatus comprising:

• a scan driving circuit for sequentially outputting a scan driving signal to the plurality of scan lines to sequentially set the display pixels in a selected state;
• a polarity reversal signal generating section for outputting a reversal signal having a polarity reversed at a time corresponding to a horizontal synchronizing signal based on the video signal;
• and
• a signal driving circuit comprising a gradation voltage generating section for generating a plurality of gradation voltages corresponding to the number of gradation levels in display data based on the video signal and reversing polarities of the gradation voltages in response to a polarity reversal timing in the reversal signal, and an applying circuit section for every predetermined number of the plurality of signal lines, for generating a display signal voltage corresponding to the display data on the basis of the plurality of gradation voltages and for sequentially applying the display signal voltage to each of the predetermined number of signal lines,
• wherein the time when the polarity reversal signal generating section reverses the reversal signal is set to occur before a timing for the next horizontal synchronizing signal and after completion of application of the display signal voltage to the plurality of signal lines.
