Beschreibung
Zusammenfassung:	A liquid crystal display device includes an array substrate on which a plurality of thin film transistors are arranged, a counter substrate arranged to face the array substrate, a liquid crystal layer interposed between the array substrate and the counter substrate, and a liquid crystal panel of a transverse field system in which liquid crystal is driven by an electric field generated in a direction parallel to the array substrate and the counter substrate. The liquid crystal panel includes a first alignment film provided on the array substrate side, and a second alignment film provided on the counter substrate side. The first and second alignment films have photo-alignment properties. At least one of the first and second alignment films has a surface on which weak rubbing treatment is performed, of which pushing amount of the rubbing roller in the rubbing treatment is in the range of 0.01 to 0.30 mm.
