Functional film and method for producing functional film

A functional film comprising:

• a substrate;
• a first functional layer having one or more combinations of an inorganic layer and an organic layer serving as a base substrate of the inorganic layer, formed on one surface of the substrate;
• a second functional layer formed on the surface of he first functional layer, with the surface being on the side opposite to the substrate;
• a light diffusion layer formed on the surface of the substrate, with the surface being on the side opposite to the surface on which the first functional layer is formed;
• and
• a diffusion layer-side surface layer having a support and an adhesive layer, formed on the surface of the light diffusion layer.

A functional film comprising:

• a functional film including a substrate, a first functional layer having one or more combinations of an inorganic layer and an organic layer serving as a base substrate of the inorganic layer, formed on one surface of the substrate, a light diffusion layer formed on the surface of the substrate, with the surface being on the side opposite to the surface on which the first functional layer is formed, and a diffusion layer-side surface layer having a support and an adhesive layer, formed on the surface of the light diffusion layer;
• a gas barrier film;
• and
• a quantum dot layer sandwiched between the functional film and the gas barrier film, with the diffusion layer-side surface layer of the functional film being on the outer side.

A method for producing a functional film, comprising:

• a step of forming a first functional layer having one or more combinations of an inorganic layer and an organic layer serving as a base substrate of the inorganic layer, on one surface of a substrate;
• a step of forming a functional layer-side surface layer on the surface of the first functional layer, with the surface being on the side opposite to the substrate;
• a step of forming a light diffusion layer on the surface of the substrate, with the surface being on the side opposite to the surface on which the first functional layer is formed, after forming the functional layer-side surface layer;
• and
• a step of forming a diffusion layer-side surface layer having a support and an adhesive layer, on the surface of the light diffusion layer.
