Solid like ER characteristic in SmecticA phase of a liquid crystal have been investigated utilizing a parallel-plate type rheometer. Since the smectic liquid crystal has the yield property which is controllable with electric field and temperature conditions, the strength of the alignment structure in the SmecticA phase was experimentally examined from the change in yield stress under various conditions. The yield processes were observed with polarized light and glass plates. It was found that the structure was averagely collapsed in the first stage of yield process under the DC electric field. On the other hand, it was considered that the layered structure generated under the AC electric field was easily slid in the yield process. Moreover, the polarized observation of the strain recovery test under the DC electric field was also conducted and it was found that the intensity of the image was also returned with strain recovery.
