The protective layer 15 is detachably attached to the upper surface of the substrate 11, the upper surface 11a of the substrate 11 is a touch surface, and the lower surface 11b of the substrate 11 is attached to the display panel 200. The first release layer 12 is releasably attached to the lower surface of the base material 11, and when the base material 11 is attached to the display panel 200, the first release layer 12 is released from the lower surface of the base material 11, for example, when one end of the base material 11 is attached to the display panel 200 first, the first release layer 12 located below the base material 11 at the end is released first, and then the first release layer 12 is released while the base material 11 is attached to the display panel 200 using a doctor blade or other means. The positioning portion 13 is disposed below the first release layer 12, and can be attached to the display panel 200 to position the display panel protective film 1 and the display panel 200 relative to each other, and in addition, the positioning portion 13 is disposed to be movable relative to the display panel 200, that is, the display panel protective film 1 can be attached to the display panel 200 in advance through the positioning portion 13, the position of the display panel protective film 1 and the display panel 200 relative to each other is adjusted according to actual conditions, and after the positions of the display panel protective film 1 and the display panel 200 are completely matched, the substrate 11 is attached to the display panel 200 while the first release layer 12 is peeled off. This ensures that the display screen protection film 1 does not deviate from the display screen 200 when the film is attached, and the appearance of the electronic product after the film is attached can be ensured. Here, the fact that the display screen protection film 1 is not deviated from the display screen 200 means that the shapes of the display screen protection film 1 and the display screen 200 are matched with each other, for example, the display screen 200 of a mobile phone generally has a button, a front camera (not shown), and the like, and correspondingly, the display screen protection film 1 of the mobile phone also has an escape hole (not shown) for the button, the front camera, and the like, and when the shapes of the display screen protection film 1 and the display screen 200 are matched with each other, the positions of the escape hole, the button, and the front camera on the display screen protection film 1 can be aligned with each other.
