Abstract
Each picture element includes first and second sub-picture elements, each of which includes a liquid crystal capacitor and at least one storage capacitor. After a display voltage representing a certain grayscale level has been applied to the respective sub-picture element electrodes of the first and second sub-picture elements, a voltage difference ΔVα is produced between voltages to be applied to the respective liquid crystal capacitors of the first and second sub-picture elements by way of their associated storage capacitor(s). By setting the voltage difference ΔVα value of the blue and/or cyan picture element(s) to be smaller than that of the other color picture elements, shift toward the yellow range at an oblique viewing angle can be minimized.
