    • The present invention relates to a method for manufacturing an optical filter for a three-dimensional image display device, which forms an alignment layer having different orientating directions along a fine region via a one-time continuous optical orientation process. The method comprising: forming a polymer layer on a substrate; a photo-orienting step comprising positioning a pattern mask above the polymer layer, the pattern 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 pattern 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 in fine regions of the polymer layer; and forming a retardation layer on the orientation 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.
    • 本发明涉及一种用于制造三维图像显示装置的滤光器的方法,其通过一次连续的光学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; 一种光取向步骤,包括在聚合物层上方定位图案掩模,图案掩模具有交替的光透射区域和布置在水平和垂直方向的光屏蔽区域以选择性地透射不同的偏振光,将偏振片定位在图案掩模上方 偏振器具有透射不同偏振光的两个可区分的区域,并且从偏光镜的上方向紫外光照射到聚合物层上,从而在聚合物层的细微区域形成具有不同取向方向的取向层; 并在取向层上形成延迟层。 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,与常规技术相比,光取向处理和制造滤光器的方法被简化。 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成品率和生产率。
