Abstract
A color liquid crystal display device such as a television receiver employing an array of R, G and B color filters and corresponding liquid crystal display elements, having the color filters arranged in different sequences in mutually adjacent scanning lines, and having a line memory in which display data for the R, G and B display elements of each display line are successively stored and applied to a drive circuit, is provided with color signal processing circuits for controlling R, G and B digital color signals which act to set these color signals into the line memory at the start of each horizontal scanning interval in a correct array sequence for the line of display elements which will be driven during that horizontal scanning interval.
