Title:
LIQUID CRYSTALLINE OLIGOMER AND LIQUID CRYSTAL ELEMENT FORMED BY USING THE SAME
Document Type and Number:
Japanese Patent JPH06273732
Kind Code:
A
Abstract:

PURPOSE: To provide the liquid crystalline oligomer with which higher speed response is possible by holding a film mixture contg. the specific liquid crystalline oligomer, low-molecular liquid crystal and an electrolyte with a pair of conductive base materials, at least one of which are transparent.

CONSTITUTION: The film mixture contg. the cyclic liquid crystalline oligomer expressed by formula I, the low-molecular liquid crystal and the electrolyte is held with a pair of the conductive base materials, at least one of which are transparent. In the formula I, Z is at least one of the groups expressed by formulas II, III, etc.; A is a spacer; Y is a liquid crystal group; X is a non- liquid crystal group; n, m are integers of n≥m and the total of which is 2 to 8; m may be 0. The main chains of the side chain type macromolecular liquid crystal of this liquid crystalline oligomer are continuous to form the cyclic structure and the repeating units of the main chains are 2 to 8. In the formulas II, III, R is an arbitrary substituent. Then, the molecular weight is smaller and more affirmative than the general side chain type macromolecular liquid crystals and molecular weight distributions are eventually theoretically not generated.
