Abstract
With a field sequential method, image display having sufficiently high color reproduction is performed, and an occurrence of color breakup is more reliably suppressed. In a field sequential liquid crystal display apparatus in which a plurality of subframes including a red subframe, a green subframe, a blue subframe, and a white (common color) subframe constitutes each frame, an image data conversion unit () converts input image data (D) corresponding to red, green, and blue into driving image data (D) corresponding to the plurality of subframes, based on an adjustment coefficient (Ks) and a distribution ratio (WRs) for the white subframe, for each pixel. Two distribution ratios are selectively used as the distribution ratio (WRs). A function of obtaining a second distribution ratio (WRsv) of the two distribution ratios is set such that the distribution ratio (WRsv) increases as the adjusted brightness (brightness after amplification and compression processing) (V) for an input image becomes smaller.
