Abstract: The present invention provides a method for manufacturing a liquid crystal device having no wrinkles and distortion between a hard coat layer and a base material film, and no peeling of the hard coat layer. This method stacks a sealing layer having an ultraviolet curable adhesive; a front plate composed of a glass or an acrylic resin; an adhesive layer; and a base material film, which has a resin layer containing an adhesion improving agent, and a hard coat layer on the film surface. The resin layer contains 0.005-0.5 parts of the per 100 parts of a binder resin. The adhesive improving agent has an absorption maximum peak at a wavelength of 260-400 nm at the time of curing the sealing layer by applying ultraviolet rays from the hard coat layer side.
