Title: LIQUID CRYSTAL PANEL AND SCANNING ANTENNA
Abstract:
A liquid crystal panel P according to the present invention is provided with an liquid crystal layer LC and a pair of a first substrate 100 and a second substrate 200, which sandwich the liquid crystal layer LC, while having an alignment film M on the liquid crystal layer-side surface of one or both of the substrates. This liquid crystal panel P is characterized in that: the alignment film M comprises a carboxyl group-containing polymer that has a carboxyl group; a liquid crystal compound constituting the liquid crystal layer LC contains at least one moiety selected from the group consisting of a cyano group, a heterocyclic ring, an -OCF2- group, a carbon-carbon triple bond and a trifluoromethyl group, while having an aliphatic alkyl group at an end and not containing an isothiocyanate group; and a plurality of antenna units are arranged therein.
