3A13 V字型反転挙動を示す液晶セルにおける誘電挙動のセル厚依存性

抄録

The low-frequency dielectric response of V-shaped switching liquid crystal cells has been investigated. In V-shaped switching liquid crystal cells with their thickness less than 10 μm, one relaxation corresponding to the Goldstone mode has been observed. The dielectric strength Δε is proportional to cell thickness and the relaxation frequency f_R increases with decreasing cell thickness and attain to 10 kHz. Similar trend has already been reported for normal surface stabilized ferroelectric liquid crystal (SSFLC) cells. We will discuss about the difference between the normal SSFLC and the V-shaped switching liquid crystal cell from experimental results.
