Abstract:
A method of driving a color liquid crystal display panel including: a transparent first substrate formed with a plurality of signal electrodes and a transparent second substrate formed with a plurality of data electrodes arranged so that a face formed with said signal electrodes and a face formed with said data electrodes are opposed to each other; a liquid crystal layer sealed in a gap therebetween; pixel portions respectively constituted at portions where said signal electrodes cross over and planarly overlap said data electrodes; and color filters, in which filters of three primary colors are alternately arranged at least at positions corresponding to said pixel portions, provided on said first substrate or on said second substrate, in which a display is performed by selectively applying a voltage between said signal electrodes and said opposed data electrodes to thereby change optical characteristics of said liquid crystal layer between said signal electrode and said opposed electrode at said pixel portion, whereina normal color display of applying selection signals to said plurality of signal electrodes constituting all said pixel portions of said color liquid crystal display panel in a time division manner, and applying data signals to said data electrodes in correspondence to the selection signals applied to said signal electrodes to allow said color filters of said pixel portions to be individually selected; and a color reducing display of applying selection signals in such a manner to simultaneously select a plurality of said signal electrodes to simultaneously select said filters of a plurality of the colors arranged at positions corresponding to said plurality of signal electrodes; are selectively performed.
