Method for fabricating a laminate film and method for fabricating a display device

A method for fabricating a display device, the display device comprising a display element and an optical film placed on a viewer's side of the display element, the method comprising:

• producing the display element;
• and
• bonding the optical film to a surface of the display element on the viewer's side via an adhesive film;
• wherein the adhesive film includes a transparent support having a first adhesive layer formed on one of two opposing surfaces, the first adhesive layer comprising a material of which the cured state changes by an application of external energy, and
• the bonding of the optical film to the surface of the display element on the viewer's side comprises:
• (a) applying external energy to the first adhesive layer;
• (b) after step (a), pressing the optical film against the first adhesive layer to stick the optical film and the first adhesive layer together;
• (c) after step (b), curing the first adhesive layer to a degree of hardness with which an adhesion state between the optical film and the first adhesive layer is fixed while the optical film and the first adhesive layer are kept stuck together;
• and
• (d) after step (c), bonding the other of the two opposing surfaces of the transparent support and the display element via a second adhesive layer.

A method for fabricating a display device, the display device comprising a display element and a lens sheet placed on the viewer's side of the display element, the lens sheet having a plurality of lenticules extending parallel to one another, the method comprising:

• producing the display element;
• forming an adhesive film on the viewer's side of the display element, wherein the adhesive film comprises a first adhesive layer and a transparent substrate;
• placing the lens sheet so that the surface of the lenticules contacts the first adhesive layer;
• and
• pressing the lens sheet against the adhesive layer by applying a force in a direction of an extension of the lenticules.

A method for fabricating a display device, the display device comprising a display element and an optical film placed on a viewer's side of the display element, the method comprising:

• producing the display element;
• and
• bonding the optical film to a surface of the display element on the viewer's side via an adhesive film, wherein
• the adhesive film includes a transparent support having a first adhesive layer formed on one of two opposing surfaces, the first adhesive layer being made of a material of which the cured state changes by an application of external energy,
• the bonding of the optical film to the surface of the display element on the viewer's side comprises:
• applying external energy to the first adhesive layer;
• pressing the optical film against the first adhesive layer to stick the optical film and the first adhesive layer together;
• curing the first adhesive layer to a degree of hardness with which an adhesion state between the optical film and the first adhesive layer is fixed while the optical film and the first adhesive layer are kept stuck together;
• and
• after curing of the first adhesive layer, bonding the other of the two opposing surfaces of the transparent support and the display element via a second adhesive layer, and
• a surface protection film is provided at least on the first adhesive layer for protecting the first adhesive layer and the method further comprises peeling off the surface protection film before pressing the optical film against the first adhesive layer.
