Abstract: A laminated film includes a functional layer laminate having a wavelength conversion layer, such as a quantum dot layer, and a gas barrier film laminated on both main surfaces and sandwiching the wavelength conversion layer, and an end face sealing layer covering a region from a portion of one main surface of the functional layer laminate to a portion of the other main surface including the entirety of end face of the functional layer laminate, in which the end face sealing layer has a build-up portion formed on the main surface of the functional layer laminate, and a width of the build-up portion measured from the end face is equal to or greater than 0.01 mm and equal to or smaller than 8% of a length of the main surface.

Abstract: A coating apparatus includes a backup roller configured to support a web; a slot die disposed opposite to the backup roller, the slot die including a plurality of slots and being configured to eject a plurality of coating liquids from tips of the plurality of slots respectively so as to form beads of the coating liquids in a clearance between the web and a lip surface, which is a tip surface of the slot die, thereby coating the plurality of the coating liquids into multilayers simultaneously on the web being transported; and a depressurizing apparatus. Among the lip surfaces which sandwich the plurality of slots therebetween, a lip surface end portion on a downstream side in a transportation direction of the web of the lip surface with which an interface of the plurality of the coating liquids comes into contact has a curved shape with a convex cross-sectional shape.

Abstract: Provided is a backlight film that is used for a liquid crystal display or the like, uses a wavelength conversion film, has satisfactory durability, and enables light without color unevenness to be emitted from the backlight unit. The problem is solved by including a wavelength conversion film having a wavelength conversion layer and gas barrier films that sandwich the wavelength conversion layer; and a plurality of reflective layers provided on one main surface of the wavelength conversion film, and causing area unevenness of the reflective layer to be ±5% or less.

Abstract: An object of the present invention is to provide a laminated film including a functional layer such as a quantum dot layer and having an appropriate shape, in which a member such as a quantum dot performing a function can be prevented from deteriorating due to the permeation of oxygen or the like from an end face. The object is achieved by a laminated film including a functional layer laminate having a functional layer and a gas barrier layer laminated on the functional layer and an end face sealing layer covering at least some of end faces of the functional layer laminate, in which the planar shape of the functional layer laminate is a shape in which the corners of a polygon are cut out, or the end faces of the functional layer laminate have a tapered shape.
