ABSTRACT:
A contrast enhanced color display apparatus, capable of providing a wide variety of colors, comprises a display means for emitting at least three colors and a color filter means disposed between the display means and a viewer. The color filter means has a frequency selectivity characteristic which produces more attenuation at some non-emitted color frequencies than at other emitted color frequencies.
