Abstract
The application discloses a display screen. The display screen includes a screen body including a cover glass and a substrate glass. The cover glass and the substrate glass each has a bonding surface and an outer surface opposite to the bonding surface. The outer surfaces of the cover glass and the substrate glass are provided with a cracking prevention layer at least in a peripheral region of a predetermined slotted region of the screen body. In a screen body cutting method disclosed in the application, cracking prevention layers are formed on the outer surfaces of both the cover glass and the substrate glass, so as to reduce the edge cracking or breaking of the screen body during the slotting and to reduce crack generated in the cover glass and the substrate glass, thereby improving overall strength of the screen body and increasing the yield of the product.
