The present invention relates to a display protective film including no base film, and the display protective film includes a transparent coating layer and a surface-protective coating layer. The protective film of the present invention is attached to whole surfaces of a flat portion and a curved portion. Accordingly, there is no peeling phenomenon on the curved portion. The protective film is also excellent in preventing the breakage of glass due to impact and preventing contamination. Moreover, scratches that may occur in outdoor activities are restored, and indentation marks made by a stylus pen when writing with the stylus pen are immediately restored, so that a clean screen is always maintained.
