Without changing a manufacturing process of a liquid crystal layer, a light-shielding layer is disposed between each film layer of the polarizer or on the edge of each film layer, and the polarizer is disposed on the liquid crystal layer to achieve the bezel-free shading, so that no light leakage occurs in the display device and the display quality of the display device is improved. | 2022-06-23 |
