Abstract

We have succeeded in observing the structure of the polymer-dispersed liquid crystal cell using SHG laser scanning microscopy combined with the Z polarization generator we have developed. The SHG phenomenon should occur in the boundary between LC molecules and the polymer surface where the inversion symmetry of LC molecules is lost. This method has the advantage of non-destructive measurement compared with the SEM imaging method.
