DIHYDRONAPHTHALENE DERIVATIVE, LIQUID CRYSTAL COMPOSITION CONTAINING THE SAME AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal compound having an improved liquid crystal temperature range, improving compatibility with other liquid crystal materials or without depraving the compatibility and effectively decreasing the response and threshold voltage, to provide a practical liquid crystal composition using the compound, and to provide a liquid crystal display element using the compound. SOLUTION: This compound is represented by the general formula (1), the liquid crystal composition containing the compound is provided and the liquid crystal display element is also provided. The liquid crystal compound is an excellent material for a high speed liquid crystal display and has effect for decreasing the threshold voltage and so has large effect for electric power saving for the liquid crystal display.
