| description | PROBLEM TO BE SOLVED: To provide a ferroelectric liquid crystal(LC) material having a wide driving temperature margin and capable of attaining stable drive also against a temperature change, an LC element using the LC material and method for manufacturing the LC element. SOLUTION: A τ-Vmin mode ferroelectric LC material is used as a ferroelectric LC material to be applied to an LC layer for an LC element so that voltage Vk for diverging the value of pulse width τ to infinity in a voltage area more than minimum voltage Vmin in a τ-V curve at the time of impressing monopulse voltage satisfies |ΔVk /dΔT| |
