| 1. A liquid crystal display device comprising:
color filter portions each having a plurality of colored layers in a unit pixel;
a liquid crystal layer for controlling the amount of light passing through the color filter portions; and
an illuminating unit for emitting light through the colored layers and the liquid crystal layer,
wherein the color filter portion has, in the unit pixel, blue, green, and red colored layers respectively having blue, green,
and red transmittance peak wavelengths at blue, green, and red regions respectively, and a cyan colored layer having a cyan
transmittance peak wavelength between the blue transmittance peak wavelength and the green transmittance peak wavelength,
the cyan transmittance peak wavelength having a peak transmittance (%) that is greater than a peak transmittance (%) of the
blue transmittance peak wavelength, and
the illuminating unit has a cyan emission brightness peak wavelength corresponding to the cyan transmittance peak wavelength
in the spectral characteristic of the cyan colored layer, and an emission brightness at a blue emission brightness peak wavelength
that is greater than an emission brightness at the cyan emission brightness peak wavelength.
