摘要： The present application relates to a polarizing plate and a display device including the same. The present application can provide a polarizing plate comprising a retardation layer exhibiting ultraviolet blocking characteristics even in a state where any ultraviolet absorber or light stabilizer is not blended. In addition, the present application can provide a polarizing plate which can be used alone or in combination with an appropriate sunscreen or a light stabilizer as needed to selectively block ultraviolet rays in a region requiring blocking, without affecting display performance, such as color senses and image quality, of a display device, can also be formed thinly without requiring a separate ultraviolet blocking layer, and also has excellent durability, because the polarizing plate exhibits a certain ultraviolet blocking property even in the absence of an ultraviolet absorber or light stabilizer.

摘要： The present invention relates to a method for manufacturing an optical filter for a stereoscopic image display device, which forms an alignment layer having different orientating directions along a fine region via a one-time continuous photo orientation process. The method comprising: forming a polymer layer on a substrate; a photo-orienting step comprising positioning a patterned mask above the polymer layer, the patterned mask having alternating light transmission regions and light shield regions arranged in both horizontal and a vertical directions to selectively transmit different polarized light, positioning a polarizer above the patterned mask where the polarizer has two distinguishable regions that transmit different polarized light, and downwardly irradiating UV light onto the polymer layer from above the polarizer, thereby forming an alignment layer having different orientating directions according to fine regions of the polymer layer; and forming a retardation layer on the alignment layer. The alignment layer in which the fine regions with different orientating directions are formed alternately and continuously is obtained via a one-time continuous photo-orientation process. Therefore, the photo-orientation process and the method for manufacturing the optical filter are simplified in comparison with the conventional art. As a result, the process yield and productivity in the manufacturing of an optical filter for a 3D image display device are improved.
摘要翻译：本发明涉及一种用于制造立体图像显示装置的滤光器的方法，该方法通过一次连续的光取向工艺沿着细微区域形成具有不同取向方向的取向层。该方法包括：在基底上形成聚合物层; 光取向步骤包括将图案化掩模定位在聚合物层上方，图案化掩模具有交替的光透射区域和布置在水平和垂直方向上的光屏蔽区域以选择性地透射不同的偏振光，将图案化掩模上方的偏振片定位在偏振器具有透射不同偏振光的两个可区别的区域，并且从偏光镜的上方向紫外光照射到聚合物层上，从而根据聚合物层的细小区域形成具有不同取向方向的取向层; 并在对准层上形成延迟层。通过一次连续的光取向工艺获得交替连续地形成具有不同取向方向的微细区域的取向层。因此，与现有技术相比，光取向处理和制造滤光器的方法简单。结果，改善了用于3D图像显示装置的滤光器的制造中的工艺产量和生产率。
