Protective element and method for manufacturing display device
A protective element includes a protective film including a first surface and a second surface opposite to the first surface; a first adhesive layer including an adhesive region on the first surface of the protective film; a first release film on the first adhesive layer; a second adhesive layer on the second surface of the protective film; a second release film on the second adhesive layer; a non-adhesive region located to surround the adhesive region, the non-adhesive region including a non-adhesive layer located between the first adhesive layer and the first release film; and a cutting portion located in the non-adhesive region and, as seen in a cross-sectional view, extending from a top surface of the protective film to a bottom surface of the non-adhesive layer.
1. A protective element, comprising:
a protective film including a first surface and a second surface opposite to the first surface;
a first adhesive layer including an adhesive region on the first surface of the protective film;
a first release film on the first adhesive layer;
a second adhesive layer on the second surface of the protective film;
a second release film on the second adhesive layer;
a non-adhesive region located to surround the adhesive region, the nonadhesive region including a non-adhesive layer located between the first adhesive layer and the first release film; and
a cutting portion located in the non-adhesive region and, as seen in a cross-sectional view, extending from a top surface of the protective film to a bottom surface of the non-adhesive layer.
2. The protective element according to claim 1 , wherein
the adhesive region includes a first adhesive region and a second adhesive region,
the first adhesive region is an adhesive surface corresponding to a display region on a substrate, and
the second adhesive region is an adhesive surface corresponding to a peripheral region on the substrate, the peripheral region including at least one of a terminal portion and a driving circuit.
3. The protective element according to claim 2 , wherein
the first adhesive region is larger than the display region, and
the second adhesive region is larger than the peripheral region.
4. The protective element according to claim 3 , wherein the non-adhesive layer is formed of varnish or medium ink.
5. A method for manufacturing a display device, the method comprising:
peeling the first release film of the protective element according to claim 3 to expose the first adhesive layer and the non-adhesive layer;
pasting a first surface of the substrate and the first adhesive layer of the protective element to each other; and
peeling the second adhesive layer, the second release film, and a part of the non-adhesive layer, a part of the first adhesive layer and a part of the protective film, the parts being outer to the cutting portion.
6. The method for manufacturing a display device according to claim 5 , wherein the substrate is foldable.
7. The method for manufacturing a display device according to claim 5 , wherein the display region includes organic EL elements.
