PROBLEM TO BE SOLVED: To provide a potential generating circuit capable of suppressing variance in white on a liquid crystal panel even if white light of a backlight unit varies.SOLUTION: The highest potential among a reference potential and potentials obtained by dividing an input potential Vis denoted as Vand the second potential is denoted as V. The potential Vis output as a potential for making pixels of B (blue) have maximum luminance. Further, a first switch 50 selects an externally specified potential among the potential Vand its peripheral potentials Vto V. The potential selected by the first switch 50 is output as a potential for making pixels of R (red) and pixels of G (green) have maximum luminance. |
