    Abstract: A screen protection device for protecting a display screen of an electronic apparatus includes: a tempered glass sheet, a mask layer, an optical clear adhesive layer, and an adhesive layer. The mask layer is positioned on the tempered glass sheet and defines a transparent region for the screen protection device. The optical clear adhesive layer is positioned on the tempered glass sheet and covers the transparent region, but does not cover the mask layer. The adhesive layer is positioned on the mask layer and the optical clear adhesive layer, and is utilized for detachably attaching to the display screen of the electronic apparatus. A thickness of the optical clear adhesive layer is at least 80% of a thickness of the mask layer.
