Abstract:
Disclosed herewith a liquid crystal display apparatus, which includes a liquid crystal display panel that employs the delta arrangement; a subtractive color processing circuit that carries out a subtractive color processing for input image data, thereby generating subtractive color image data; and data line driving circuit that drives the liquid crystal display panel in response to the subtractive color image data. The subtractive color processing circuit carries out a weighting processing that increases or decreases the subtractive color image data according to a line that includes a sub-pixel to be subjected to a subtractive color processing, then carries out an error diffusion processing for the result of the weighting processing, thereby generating subtractive color image data. The subtractive color processing circuit carries out the weighting processing so as to increase the subtractive color image data corresponding to a line and decrease the subtractive color image data corresponding to another line.
