Abstract
A display device includes a display panel comprising a display area, a cover window disposed on an upper surface of the display panel, and a protection member disposed on a lower surface of the display area of the display panel. A material of the protection member has an elastic modulus of 4 GPa or less at a glass transition temperature of the material and a contraction rate of 20% or more at the glass transition temperature.

A display device comprising:
- a display panel comprising a display area;
- a cover window disposed on an upper surface of the display panel;
- and
- a protection member disposed on a lower surface of the display area of the display panel,
- wherein a material of the protection member has:
- an elastic modulus of 4 GPa or less at a glass transition temperature of the material, and
- a contraction rate of 20% or more at the glass transition temperature.

A display device comprising:
- a display panel comprising a display area and a bonding area spaced apart from the display area;
- a cover window disposed on the display area of the display panel;
- a first protection member disposed under the display area of the display panel;
- and
- a second protection member disposed under the bonding area of the display panel and spaced apart from the first protection member,
- wherein a contraction rate of the second protection member is smaller than a contraction rate of the first protection member.

A method of fabricating a display device, the method comprising:
- preparing a display panel, a first protection member, and a second protection member;
- attaching a first protection member and a second protection member to a lower surface of the display panel so that the first protection member is separated from the second protection member on the lower surface of the display panel;
- aligning a cover window on an upper surface of the display panel and a guide member on a lower surface of the display panel;
- pressing the cover window and the guide member against the upper and lower surfaces of the display panel, respectively;
- heating, after the pressing, the first protection member of the display panel through the guide member;
- and
- removing the guide member,
- wherein an elastic modulus of the second protection member is greater than an elastic modulus of the first protection member.
