In a display device having a color filter, a color material dispersed layer having the function of absorbing light of specific wavelengths in the visible light beam region is provided on the optical path so that the light absorption peak of this color material dispersed layer in the visible light beam region is located in the range of +/-30 nm from the overlap point in the spectral transmission properties of each color of the color filter. Further, the color material dispersed layer is provided on a filter as a constituent part of the back light of the display. This filter has, as its substrate, a thermoplastic resin having a thickness of 30 - 350 micrometers and has a transmission in the maximum absorption wavelength in the color material dispersed layer of not more than 75%. The back light has, as its light source, a fluorescent lamp comprising a three band tube, and its emission color is subjected to color correction by an auxiliary filter having an organic color material dispersed layer provided on the illuminating light path. <IMAGE>
