Abstract
A liquid crystal display device of this invention includes a yellow guest-host liquid crystal layer, a magenta guest-host liquid crystal layer, and a cyan guest-host liquid crystal layer. The absorption spectrum of each color has at least two absorption peaks, and the absorbance of the second largest absorption peak is 80% or more that of the largest absorption peak.

A liquid crystal display device comprising a yellow guest-host liquid crystal layer, a magenta guest-host liquid crystal layer, and a cyan guest-host liquid crystal layer, wherein an absorption spectrum of each color has at least two absorption peaks, and an absorbance of the second largest absorption peak is not less than 80% of an absorbance of the largest absorption peak.
A liquid crystal display device comprising a yellow guest-host liquid crystal layer, a magenta guest-host liquid crystal layer, and a cyan guest-host liquid crystal layer, wherein a half-width of an absorption spectrum of yellow is 60 nm to 110 nm, a half-width of an absorption spectrum of magenta is 70 nm to 110 nm, and a half-width of an absorption spectrum of cyan is 80 nm to 130 nm.
A liquid crystal display device comprising a guest-host liquid crystal layer, wherein said guest-host liquid crystal layer contains, as guest dyes, a fluorescent dichroic dye and a quenching dichroic dye which kills fluorescence resulting from said fluorescent dichroic dye.
