PURPOSE:To obtain a color display device which has high color purity and superior color reproducibility by using a light source which has a light emission peak in the main wavelength region of transmission spectral characteristics of each color element of a color filter. CONSTITUTION:An R, a G, and a B color filters 1 are arranged corresponding to respective fine picture elements of a liquid-crystal optical shutter 6. Luminous flux from a three-wavelength light emitting fluorescent tube which has a light emission peak in the main wavelength region (R, G, B) of transmission spectral characteristics of the filters 1 is passed through a optical guide plate 8 made of transparent resin to obtain plane luminous flux, which is incident to the color filters 1 through a liquid-crystal shutter 6, obtaining a sharp image with high color purity. |
