Patent ID: 7396573

Claim:
A liquid crystal display element that is a layered member comprising: a liquid crystal layer, provided between a pair of electrodes, at least one of which is a transparent electrode, and the liquid crystal layer including 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; and a reflection layer; the liquid crystal display element displaying an image by reflecting incident light -(Het) j -[(B 1 ) p -(Q 1 ) q -(B 2 ) r ] n -C 1 Formula (1) wherein, in forumla (1), Het represents an oxygen atom or a sulfur atom; B 1 and B 2 each independently represent a divalent arylene group, a heteroarylene group or a divalent alicyclic hydrocarbon group; Q 1 represents a divalent linking group; C 1 represents an alkyl group, a cycloalky group, an alkoxy group, an alkoxycarbonyl group, an acyl group or an acyloxy group; j represents 0 or 1; p, q and r each independently represent an integer of to 0 to 5; n represents an integer of 1 to 3; (p+r)×n is an integer of 3 to 10; when p is 2 or larger, two or more groups represented by B 1 may be the same or different; when q is 2 or larger, two or more groups represented by Q 1 may be the same or different; when r is 2 or larger, two or more groups represented by B 2 may be the same or different; and when n is 2 or larger, two or more groups represented by [(B 1 ) p -(Q 1 ) q -(B 2 ) r ] may be the same or different, the low molecular weight gelling agent having (i) a linear (per) fluoroalkyl group having 4 to 20 carbon atoms that may be substituted at a terminal, (ii) a linear alky group having 4 to 20 carbon atoms that may be substituted at another terminal, and (iii) at least two hydrogen-bonding groups.
