Specifically, it is preferred that the contrast C<SUB>R </SUB>of the red color pattern 10 R, the contrast C<SUB>G </SUB>of the green color pattern 10 G, and the contrast C<SUB>B </SUB>of the blue color pattern 10 B fulfill the relationship C<SUB>R</SUB><C<SUB>G</SUB><C<SUB>B</SUB>, as well as the relationship C<SUB>R</SUB>:C<SUB>G</SUB>=1.0:1.2 to 1.0:2.5, and C<SUB>R</SUB>:C<SUB>B</SUB>=1.0:1.5 to 1.0:4.5. The C<SUB>R </SUB>is preferably 700 or more.
