Abstract
In a gas barrier laminate film comprising a gas barrier layer laminated on at least one surface of a support, the surface of the support on the side opposite to the surface laminated with the gas barrier layer is made to have an Ra value of 1 to 20 nm. A gas barrier laminate film that can prevent cracks generated by displacement of rolled film, slacks and wrinkles during rolling up and transportation in the production process of the film and thus can be produced with a high yield, a method for producing the same and an image display device utilizing the film are provided.
