Abstract
(EN)
The present invention provides an alignment assistant which is capable of ensuring the storage stability of a liquid crystal composition, while being capable of having liquid crystal molecules spontaneously align. The present invention also provides: a liquid crystal composition which has excellent storage stability, and which enables the achievement of a liquid crystal display element wherein liquid crystal molecules are well aligned; and a liquid crystal display element which uses this liquid crystal composition. This alignment assistant makes liquid crystal molecules align spontaneously. This alignment assistant is characterized by containing a first compound that has a polar group and a second compound that is different from the first compound but has the same polar group.

La présente invention concerne un assistant d'alignement étant capable d'assurer la stabilité au stockage d'une composition de cristaux liquides, tout en étant capable d'avoir des molécules de cristaux liquides s'alignant spontanément. L'invention concerne également : une composition de cristaux liquides qui présente une excellente stabilité au stockage et qui permet la réalisation d'un élément d'affichage à cristaux liquides dans lequel les molécules de cristaux liquides sont bien alignées ; et un élément d'affichage à cristaux liquides qui utilise cette composition de cristaux liquides. Le présent assistant d'alignement fait s'aligner spontanément les molécules des cristaux liquides. Le présent assistant d'alignement est caractérisé en ce qu'il contient un premier composé qui a un groupe polaire et un second composé qui est différent du premier composé mais a le même groupe polaire.
