Abstract
Chevron layer structures and focal conics in chiral smectic C liquid crystals were investigated by means of polarizing microscope observation and X-ray analysis for two kinds of cells (parallel cells and antiparallel cells) aligned on obliquely evaporated SiO film. For parallel cells, symmetric chevron layer structures and symmetric focal conics were formed. For antiparallel cells, asymmetric chevron layer structures and asymmetric focal conics were formed.
