The screen cover 3 of this embodiment differs from the three embodiments described above in that the composite sheet layer 3 further includes a third layer 3113, and the third layer 3113 is provided on the surface of the first layer 3111 facing away from the second layer 3112. In this embodiment, the material of the third layer 3113 includes polymethyl methacrylate. The polymethyl methacrylate is a transparent material, and is favorable for improving the light transmittance of the screen cover plate 3. Moreover, the polymethyl methacrylate has better hardness and rigidity, so that the hardness and rigidity of the screen cover plate 3 can be further increased, the mobile terminal 100 is prevented from being broken due to falling or collision, and the display screen 1 is effectively protected.
