摘要： The present invention relates to a retardation film having a homeotropic alignment liquid crystal film, a polarizing film, an IPS (In-Plane Switching) mode liquid crystal display and a method for preparing the same. More particularly, the present invention relates to a homeotropic alignment liquid crystal film prepared from a liquid crystal mixed solution containing a poly-merizable reactive liquid crystal monomer so as to improve a viewing angle characteristic of an ISP mode liquid crystal display and reduce a color shift; a retardation film prepared by integrating an oriented retardation film and a method for preparing the same; a polarizing film having the retardation film located between a polarizing element or plate and a liquid crystal cell and a method for preparing the same; and an IPS mode liquid crystal display having the polarizing film. There is an advantage in that since a homeotropic alignment liquid crystal film with a retardation of a thickness direction is prepared using a liquid crystal mixed solution containing a reactive liquid crystal monomer, a retardation film according to the present invention is not required for high-temperature heat treatment and cooling processes so that it can be applied to a high-speed continuous process. Further, there is an advantage in that a retardation film having an oriented retardation film integrated with the homeotropic alignment liquid crystal film is arranged between a polarizing element or polarizing plate of an IPS mod liquid crystal display and a liquid crystal cell so that a contrast ratio can be increased up to about 1520%, and a color shift characteristic can be also improved.

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.
