Abstract: A display device includes a protective film, a display panel, and a conductive film package. The protective film has a first area, a second area, and a third area positioned between the first area and the second area. The display panel is disposed in the first area and the third area on the protective film. The conductive film package is disposed on the display panel, and is in contact with the protective film positioned in the second area. In this manner, a defect of the substrate included in the display panel and a defective adhesion between the conductive film package and the display panel may be avoided.
