Pattern formation processes and equilibrium shapes of smectic-A domains grown from an isotropic phase in the Cano wedges have been observed in the mixture of octyloxycyanobiphenyl and dodecyl alcohol. The Cano wedges enable us to observe cell thickness (L) dependence of the pattern formation. In the region of L > 10μm, three dimensional growth and equilibrium shapes that have been reported earlier in the 50μm-thick cells were observed. On the other hand, in the region of L < 10μm, the observed patterns are essentially characterized by plane curves. For instance, circular filaments, which were rarely found for L > 10μm, developed from buckled filaments were reproducibly observed as equilibrium shapes. It is shown that these experimental findings can be explained in terms of the theory for smectic-A filaments [H. Naito, M. Okuda and Z. Ou-yang, Phys. Rev. E 55, 1655 (1997)].
