| 摘要 |
The invention provides a liquid crystal display element and a light-modulating material each containing at least one low molecular weight gelling agent, at least one dichroic dye having a substituent represented by formula (1) and at least one host liquid crystal between a pair of electrodes at least one of which is a transparent electrode. Representations in formula (1) are: Het, O or S; B<SUP>1 </SUP>and B<SUP>2</SUP>, divalent arylene, heteroarylene or alicyclic hydrocarbon group; Q<SUP>1</SUP>, divalent linking group; C<SUP>1</SUP>, alkyl, cycloalkyl, alkoxy, alkoxycarbonyl, acyl or acyloxy group; j, 0 or 1; p, q and r, an integer 0 to 5; n, an integer 1 to 3; and (p+r)xn is an integer 3 to 10. <?in-line-formulae description="In-line Formulae" end="lead"?>-(Het)<SUB>j</SUB>-[(B<SUP>1</SUP>)<SUB>p</SUB>-(Q<SUP>1</SUP>)<SUB>q</SUB>-(B<SUP>2</SUP>)<SUB>r</SUB>]<SUB>n</SUB>-C<SUP>1</SUP> Formula ( 1 )<?in-line-formulae description="In-line Formulae" end="tail"?>
