Abstract
A method of manufacturing a display apparatus is provided as follows. A substrate having a display portion on an upper surface of the substrate is prepared. A protection film having an opening is attached to a lower surface of the substrate so that the protection film overlaps the display portion. A support film is attached to the lower surface so that the support film is disposed within the opening of the protection film. A driving circuit chip is attached to the upper surface so that the driving chip is spaced apart from the display portion and the opening. At least a part of the support film is removed. The substrate is bent along a longitudinal direction of the opening.
Claims20
A display apparatus comprising:
- a substrate having a first area, a second area and a bending area between the first area and the second area, wherein the bending area is bent to have a curved lower surface;
- a display portion disposed on an upper surface of the first area of the substrate;
- a protection film disposed on a lower surface of the first area of the substrate and comprising a protection film base and a first adhesive layer;
- and
- a second adhesive layer disposed on the curved lower surface of the bending area of the substrate,
- wherein a hardness of the second adhesive layer is higher than a hardness of the first adhesive layer and
- wherein the protection film has an opening exposing the curved lower surface of the bending area of the substrate.
A display apparatus comprising:
