Abstract:
As a substrate gets larger, time of manufacture is increased due to the repetition of film formations and etchings; waste disposal costs of etchant and the like are increased; and material efficiency is significantly reduced. A base film for improving adhesion between a substrate and a material layer formed by a droplet discharge method is formed in the invention. Further, a manufacturing method of a liquid crystal display device according to the invention includes at least one step for forming the following patterns required for manufacturing a liquid crystal display device without using a photomask: a pattern of a material layer typified by a wiring (or an electrode) pattern, an insulating layer pattern; or a mask pattern for forming another pattern.
