A color Liquid Crystal display (LCD) device for displaying a color image using at least four different primary colors, the device including an array of Liquid Crystal (LC) elements, driving circuitry adapted to receive an input corresponding to the color image and to selectively activate the LC elements of the LC array to produce an attenuation pattern corresponding to a gray-level representation of the color image, and an array of color sub-pixel filter elements juxtaposed and in registry with the array of LC elements such that each color sub-pixel filter element is in registry with one of the LC elements, wherein the array of color sub-pixel filter elements comprises at least four types of color sub-pixel filter elements, which transmit light of the at least four primary colors, respectively.
A color display device for displaying a color image, comprising an array of rectangular color sub-pixel elements including sub-pixel elements of n different non-white colors, wherein n is greater than three, wherein each sub-pixel element is adjacent on a first axis to two different colored sub-pixels from said sub-pixel element, and wherein each sub-pixel element is adjacent on a second axis, orthogonal to said first axis, to two sub-pixels, each having the same color as said sub-pixel element, wherein each of said n different non-white colors is associated with filter elements having a transmission bandwidth, and wherein the transmission bandwidth of a first of said n non-white colors substantially overlaps with the transmission bandwidth of a second of said n non-white colors.
