Abstract
A liquid crystal panel includes substrates, a liquid crystal layer between the substrates, a spacer provided on an opposite surface of one of the substrates, and an alignment film provided on an opposite surface of another substrate. The display surface is curved around a curved axis or formed to be bendable around the curved axis, and the spacer directly or indirectly abuts on the alignment film provided on the opposite surface of the other substrate. The alignment film is a horizontal alignment film that contains a polymer having an alkylene chain structure having two or more carbon atoms in a main chain and allows liquid crystal molecules in the liquid crystal layer to be aligned horizontally to the alignment film, and in the alignment film provided on the opposite surface of the other substrate, the polymer is aligned such that the alkylene chain structure extends parallel to the curved axis.
