Abstract: This application provides a display screen, a display screen protective film, and an electronic device. A transmissive layer of the display screen has a first surface away from a display panel, an orthographic projection of each micro structural unit on the first surface and along a thickness direction is located in a pixel region, and a projection area of the micro structural unit is less than or equal to an area of the pixel region. The micro structural unit may be a curved surface. In this embodiment of this application, the pixel region may include a region in which a sub-pixel is located on the display panel, and a spaced region between the sub-pixel and another sub-pixel that is located around the sub-pixel and adjacent to the sub-pixel. In the foregoing display screen, each micro structural unit mainly bends a display light ray of one sub-pixel. This helps reduce a difference in light refraction degrees between different sub-pixels, and further helps optimize a flash point.
