Abstract
A notch filter is provided in a RGB color twisted nematic liquid crystal display (LCD) apparatus, the notch filter preferably being located between the light source and the display panel. Undesirable peak(s) (e.g. blue-green) in the light rays from the source are substantially reduced or eliminated by the notch filter thereby improving the color saturation characteristics of the image reaching the viewer.
