摘要： A liquid crystal device comprising a pair of substrate, at least one of them being transparent, and a light-control layer supported therebetween, wherein said light-control layer comprises a liquid crystal material showing positive dielectric anisotropy and a transparent solid substance, said liquid crystal material forming a continuous phase, and said transparent solid substance existing in said continuous phase in the form of dispersed particles or a three-dimensional network. The device exhibits a clear threshold voltage, a high fast response time and a highly contrast display with a low applied voltage.

摘要： A oligosaccharide aromatic glycoside sulfate or a physiologically acceptable salt of the same which is formed from same or different monosaccharides bonded by glycoside bonds, wherein the hydrogen atom in the hydroxyl group at the position-1 carbon atom at the terminal of the oligosaccharide is substituted with a group represented by Formula (I):
        - Y - (O) n - R   (I)
(in the formula, R represents an alkyl group having 1-18 carbon atoms, n is 0 or 1, O represents an oxygen atom, and Y represents an allylene group) and at least 10% of the remaining hydroxyl groups of the sugar subunits have been subjected to sulfated esterification; an anti-viral agent containing this oligosaccharide aromatic glycoside sulfate or physiologically acceptable salt of the same as an active component; and a oligosaccharide aromatic glycoside which functions as a production intermediate are disclosed. The anti-viral agent exhibits low toxicity and superior anti-viral activity, and is especially effective against viruses which are known to cause AIDS.
