A display apparatus and a driving chip mounting film in the display apparatus, capable of simplifying a manufacturing process and reducing a process time. The display apparatus includes an insulating substrate; a display device formed on the insulating substrate and for defining an image display unit; pads formed on the insulating substrate and electrically connected to the display device; a first circuit substrate disposed at and separate from a first side of the insulating substrate; and a number of driving chip mounting films including one-side ends electrically connected to the first circuit substrate, and other-side ends electrically connected to the pads. A number of driving chips are mounted on each of the number of driving chip mounting films.
