Abstract

Abstract To improve yield in the liquid crystal display device manufacturing process, at least either of an interconnection protective film for protecting the conductive interconnection formed on the substrate to electrically connect the transparent electrode film in the liquid crystal cells to the liquid crystal cell driving semiconductor chip and a liquid crystal molecule aligning film formed within the liquid crystal cells are made of benzocyclobutene resin. The benzocyclobutene resin is polyorganosiloxane crosslinked bisbenzocyclobutene.
