| Abstract: | By using an optical system sensitive to small changes in birefringence, we have measured the Leslie threshold field for distorition in a twisted nematic (TN) cell. The compound used in the measurement was 4'-n-heptyl-4-cyanobiphenyl (7CB) for which we have independently measured all the three elastic constants. With these data we have verified Leslie's expression for the threshold field for the TN cell. |
