Mesophase in which disc-shaped molecules, the disc-shaped moieties of macromolecules or wedge-shaped molecules assemble themselves in columns packed parallel on a two- dimensional lattice, but without long-range positional correlations along the columns.

Note: Depending on the order in the molecular stacking in the columns and the two- dimensional lattice symmetry of the columnar packing, the columnar mesophases may be classified into three major classes: hexagonal, rectangular and oblique
