Anematic liquid crystal in contact with a solid substrate is considered. Three types of surface phenomena are discussed: anchoring, wetting and surface phase transitions, which involve symmetry breaking in the surface layer. Where possible, we reveal relations between these phenomena. We concentrate on the following problems: anchoring on anisotropic substrates, the force balance equation at the nematic-isotropic-substrate contact line, the behaviour of the line tension in the thermodynamic limit, and the onset of the smectic-A order in the surface layer close to the bulk transition to the smectic-A phase. All these problems are studied in the framework of the Landau-de Gennes formalism. Possible directions of future studies are discussed.
