ABSTRACT:
In driving a color liquid crystal panel having red, green and blue color filters, a color liquid crystal display apparatus sets signal electrodes of these three colors in a no-bias status during a non-display period of an image signal in such a manner as to permit at least two colors of the signal electrodes have mutually different effective voltages. The effective voltages in the no-bias state are set at values which provide the optimum value for .DELTA.n.multidot.d (.DELTA.n: birefringence) in accordance with cell gaps d on the signal electrodes, thereby minimizing the height difference between the color filters.
