Liquid crystal display including filter means with 10-70% transmittance in the selective reflection wavelength range

A liquid crystal display comprising:

• a plurality of liquid crystal light control layers each of which includes liquid crystal exhibiting a cholesteric phase and having a peak wavelength of a selective reflection wavelength range of a reflection spectrum in the visible wavelength range, the liquid crystal light control layers being stacked in such order that the peak wavelength of any of the liquid crystal light control layers is larger than that of the adjoining liquid crystal light control layer on the viewing side;
• and
• filter means provided on the viewing side of or in at least one of the liquid crystal light control layers,
• wherein a transmittance of the filter means is 10 to 70% in the selective reflection wavelength range of the liquid crystal light control layer situated on the viewing side of the filter means.
