Abstract
A scanning antennaaccording to the present invention is a scanning antennain which antenna units U are arranged, and includes a thin film transistor (TFT) substratethat includes a first dielectric substrate, TFTsand patch electrodessupported by the first dielectric substrate, and a first alignment film Mdisposed so as to cover the patch electrodesand other elements, a slot substratethat includes a second dielectric substrate, a slot electrodesupported by the second dielectric substrateand including slots, and a second alignment film Mdisposed so as to cover the slot electrode, a liquid crystal layer LC that is interposed between the TFT substrateand the slot substrateof which the alignment films Mand Mface each other, and a reflective conductive platethat is disposed so as to face an opposite surfaceof the second dielectric substratewith a dielectric layerinterposed therebetween. The first alignment film Mand the second alignment film Mare acrylic alignment films containing an acrylic polymer.
