Abstract
PURPOSE:To improve color balance by varying signal electrode driving voltages of at least two systems among the signal electrode driving voltages of three systems according to the transmittances of color filters R, G, B. CONSTITUTION:Voltage regulating circuits by a variable resistor 361 and a variable resistor 371 are respectively provided to a bias voltage generating circuit 36 for G and a bias voltage generating circuit 37 for B among bias voltage generating circuits 35-37 and, therefore, the display colors in a color liquid crystal panel 30 can be regulated by the voltage regulation thereof. The effective values to be acted on the liquid crystal are, therefore, equaled in R, G and B by regulating the variable resistors 361, 371 even if the film thicknesses of the color filters R, G, B fluctuate. The high display grade is thus obtd.
