A novel colored cholesteric display obtained by oriented cholesteric liquid crystal (LC) molecules confined in elliptic droplets dispersed in an organic-monomer matrix was analyzed. The cholesteric LC mixtures were subjected to a thermally induced phase separation between the cholesteric phase and the monomer matrix to obtain a confined homogenous cholesteric phase. A crossed-polarizer optical microscopy technique was used to observe the images of the film. The results show that when the droplets reach a diameter equal to the cell thickness during the growth phase, they extend in the plane and assume the typical elliptic shape.

Abstract
A novel colored cholesteric display obtained by oriented cholesteric liquid crystal (LC) molecules confined in elliptic droplets dispersed in an organic-monomer matrix was analyzed. The cholesteric LC mixtures were subjected to a thermally induced phase separation between the cholesteric phase and the monomer matrix to obtain a confined homogenous cholesteric phase. A crossed-polarizer optical microscopy technique was used to observe the images of the film. The results show that when the droplets reach a diameter equal to the cell thickness during the growth phase, they extend in the plane and assume the typical elliptic shape.File in questo prodotto:
