抄録

Attenuated total reflection (ATR) properties have been investigated for tilt angles of liquid crystal molecules, SCB, in the liquid crystal cell with the polyimide (PI) LB alignment films on the aluminum electrodes. The ATR curves strongly depended upon the voltages applied to the cell. The resonant excitations of the surface plasmon wave modes and the guided wave ones were observed in the ATR measurements. The tilt angles of the liquid crystal molecules were calculated on the LB films and in the middle layer region of the cell by fitting the theoretical ATR curves to the experimental ones. It is thought that the ATR measurement is very useful for evaluating the aligning properties of liquid crystal molecules in liquid crystal cells.
