By preparing a color filter including blue dots whose chromaticity
coordinates (z, Z) in the XYZ colorimetric system, measured with CIE
standard light source C, satisfy the relational expressions
114>Z>-1087023z.sup.4 +3205105z.sup.3 -3545958z.sup.2
+1744329z-321773 and 0.73.ltoreq.z.ltoreq.0.81, a color filter exhibiting
an excellent color reproducibility and a high transmittance can be
realized and thus a liquid crystal display device capable of displaying as
colorful images as in CRT television sets can be achieved.
