The dependence of the alignment of liquid crystals around spherical spacers on liquid crystal materials has been studied. The non-polar LC mixture of PCH302 and PCH304 aligned vertically on the surface of spacers. On the other hand, the polar LC mixture, ZLI-1083 that is composed of PCIIs, showed tangential alignment on the surface. In the case of the mixture of non-polar LC and polar LC, both vertical and tangential alignments were observed. A fluorinated LC mixture also showed tangential alignment. The polarity of liquid crystal mixtures is suggested to play a significant role in determining the alignment.
