Abstract
A bandpass filter containing specific red dyes alone or in combination with other dyes selectively transmits predetermined primary color wavelengths as well as selectively absorbs wavelengths other than the predetermined primary color wavelength. The filter is particularly useful for enhancing the contrast of color plasma displays by absorbing visible light emitted at 590 nm from the display.
