Abstract
A display device includes a display panel folded with respect to an imaginary folding axis extending in a first direction, an anti-reflective layer disposed on the display panel, a window disposed on the anti-reflective layer, and a first adhesive layer disposed between the anti-reflective layer and the window. The first adhesive layer includes an adhesive having a change rate in a storage modulus of about 0.3 or less at a temperature of about 150 degrees Celsius (° C.) to about 200° C. with respect to the storage modulus at a temperature of about 60° C.
Claims18
A display device comprising:
- a display panel folded with respect to an imaginary folding axis extending in a first direction;
- an anti-reflective layer disposed on the display panel;
- a window disposed on the anti-reflective layer;
- and
- a first adhesive layer disposed between the anti-reflective layer and the window, the first adhesive layer comprising:
- an adhesive having a change rate in a storage modulus of about 0.3 or less at a temperature of about 150 degrees Celsius to about 200 degrees Celsius with respect to the storage modulus at a temperature of about 60 degrees Celsius,
- wherein the adhesive of the first adhesive layer has the storage modulus from about 10 kilopascals to about 50 kilopascals at the temperature of about 60 degrees Celsius.
A display device comprising:
- a display panel folded with respect to an imaginary folding axis extending in a first direction;
- an anti-reflective layer disposed on the display panel;
- a window disposed on the anti-reflective layer;
- and
- a first adhesive layer disposed between the anti-reflective layer and the window, the first adhesive layer comprising:
- an adhesive having a change rate in a storage modulus of about 0.3 or less at a temperature of about 150 degrees Celsius to about 200 degrees Celsius with respect to the storage modulus at a temperature of about 60 degrees Celsius,
- wherein one side surface of the first adhesive layer protrudes outward than one side surface of the window adjacent to the one side surface of the first adhesive layer.
A method of manufacturing a display device, the method comprising:
- attaching a first stack structure comprising a first release film, an anti-reflective layer, and a first adhesive layer disposed between the first release film and the anti-reflective layer to one surface of a display panel folded with respect to an imaginary folding axis extending in a first direction;
- and
- cutting the display panel and the first stack structure attached to the display panel using a laser beam,
- wherein a temperature of the first adhesive layer rises to a range from about 150 degrees Celsius to about 200 degrees Celsius in the cutting the first stack structure.
