    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.

    Abstract: A display device includes a display panel, a circuit board, a first conductive film, first and second lower films, and first and second adhesive layers. The display panel includes a display area and a pad area which includes a first pad part. The circuit board is attached on the display panel and includes a lead part overlapping the first pad part. The first conductive film is between the display panel and the circuit board and electrically connects the first pad part and the lead part to each other. The first and second lower films are attached to the display panel to respectively correspond to the display area and the pad area. A thickness of the second adhesive layer between the display panel and the second lower film is less than a thickness of the first adhesive layer between the display panel and the first lower film.
