Abstract
To correct the dependency of the transmissivity/applied voltage characteristics on color, a computing circuit is provided for generating corrected gray scale data by performing an addition or subtraction of the gray scale level related to at least one color. A delay circuit delays the gray scale data for uncorrected colors to maintain synchronization between the gray scale signals of all colors.
