摘要： Molecular orientation configurations across zig-zag defects and thin-line defects of the surface stabilized ferroelectric liquid crystal (SSFLC) cell are presented. The transmission spectra of the SSFLC cell of non-uniform states are numerically calculated using the asym-metric chcvron structure model. The calculations agree well with experimental results, which confirms the continuity of the N-director across the chevron interface. The color alternation of the SSFLC cell between crossed polarizers is well explained.
