[0002] A polarizer is a multilayer composite optical film that can convert natural light into light with a specific polarization direction. It is a core component in devices such as liquid crystal displays to realize image display and optical control.

[0003] According to a patent published on the China Patent Network, the patent title is "A Double-Sided Polarizing Film with Adhesion," patent application number 201410034538.4. From the inside out, it includes a polarizing film, a protective layer, and an adhesive layer. The polarizing film has a protective layer on both its upper and lower surfaces. The adhesive layer is double-sided, with one side adhering to the protective layer and the other side adhering to the terminal device using the polarizing film, forming a polarizing film with double-sided adhesion. The double-sided protective layer of this invention better protects the core polarizing film, and the double-sided adhesion allows the polarizing film to be directly bonded to the outer surface protective layer of the device screen, simplifying the manufacturing process of the display screen or touch screen and reducing production costs. In contrast, the outermost adhesive portion of the aforementioned polarizing film lacks scratch protection, making it susceptible to friction and scratches during storage or transportation, affecting its performance and reducing its lifespan.

[0004] Therefore, it is necessary to redesign the polarizer to effectively prevent the lack of scratch protection measures on its adhesive parts. Utility Model Content
