Conventional thin film transistor liquid crystal displays mainly include components such as a glass substrate, a color filter, a polarizer, an ITO conductive film, and a backlight module. Among them, the polarizer is an optical element that allows only light of a certain electric field to pass through, so that it can convert generally non-polar light (for example, light emitted by the backlight module) into polarized light. And through the steering of the liquid crystal driven by the voltage, and the corresponding color filter ' at the same time, the color, the brightness and the contrast development effect are produced, so as to achieve the purpose of displaying the image by using the backlight. Please refer to FIG. 1 , which is a schematic view showing the structure of a conventional polarizer.

However, due to the partiality, the sheet has a multi-layer structure made of different materials as described above, so that it is easy to be warped due to stress release after fabrication, and thus causes subsequent assembly of the thin film transistor liquid crystal display. The inconvenience even affects its quality. 6 200900753 First-time fit, the conventional art engineer usually protects the film 77 to report & a main +: two sheets of cellulose diacetate film 73 and to form the polarized light; 5: In the ^ cloth-adhesive layer, the release film 75 is attached and the quality is stable. _, this will increase the conditions under the conditions of the finished product to make it ‘ the process complexity of this process, the production process of the film and the production time, and the catalogue of polarizers produced by the sister is unstable.
