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.
