Abstract:
1. A liquid crystal display apparatus driving circuit, comprising a plurality of driving sections provided on a periphery of a display section in which a plurality of scanning signal lines and a plurality of video signal lines intersect with each other and a plurality of pixels are provided in a matrix manner, said plurality of driving sections each corresponding to a number of the video signal lines, said liquid crystal display apparatus driving circuit configured to selectively supply positive polarity gray scale voltages or negative polarity gray scale voltages to the video signal lines as video signals, each of the driving sections comprising: a gray scale voltage generation circuit for generating a gray scale voltage for display; and first and second gray scale voltage adjusters included in the gray scale voltage generation circuit, for increasing a positive polarity gray scale voltage and a negative polarity gray scale voltage while maintaining a voltage difference between the positive polarity gray scale voltage and the negative polarity gray scale voltage and respectively adjust a center potential of the positive polarity gray scale voltage and a center potential of the negative polarity gray scale voltage.
