Method of forming antireflection optical body, display panel, and optical film

A method of forming an antireflection optical body on an adherend, comprising:

• a pressing step of pressing a substrate film having a fine structure body at one surface side with a photocurable resin layer in a semi-cured state being formed on the fine structure body, against the adherend from an opposite surface side to the one surface side by a light guide transparent to light;
• a curing step of curing the photocurable resin layer by transmitting light through the light guide with the substrate film being pressed by the light guide;
• and
• a peeling separation step of releasing the pressing of the substrate film and peeling fixed fine structure body that is fixed to the adherend through the cured photocurable resin layer from the substrate film while separating the fixed fine structure body from fine structure body on the substrate film other than at a location fixed through the photocurable resin layer such that the fixed fine structure body is formed on the adherend as an antireflection optical body.

An optical film comprising:

• a fine recess-protrusion layer having a recess-protrusion pattern, formed on a substrate film;
• and
• a fine structure body formed on the fine recess-protrusion layer,
• wherein the optical film is pressed by a light guide transparent to light against one surface of an adherend applied with a photocurable resin, and light is transmitted through the light guide to cure the photocurable resin with the optical film being pressed by the light guide, thereby forming the fine structure body on the adherend.

An optical film comprising:

• a fine recess-protrusion layer having a recess-protrusion pattern, formed on a substrate film;
• a fine structure body formed on the fine recess-protrusion layer;
• and
• a photocurable resin layer made of a semi-cured photocurable resin, formed on the fine structure body,
• wherein the optical film is pressed by a light guide transparent to light against one surface of an adherend, and light is transmitted through the light guide with the optical film being pressed by the light guide, thereby forming the fine structure body on the one surface side of the adherend.
