Photoalignment Properties on TAC film of Photopolymer based on Photoreactive Groups for Optical Retarder film |
| 초록 |
In liquid crystal display device, the alignment of the liquid crystal molecules plays the important role to characterize the image quality of LCD. The rubbing process of conventional technique has many problems for LCD such as generation of electrostatic charge and light leakage. On the other hand, the chemical method, photoalignment process, is a non-contact method that not only solves the problem of rubbing process, but also can has the effect of increasing yield and contrast ratio. Therefore, many kind of research have been conducted on photoalignment process. In this study, we have synthesized the photopolymer based on chalcone moiety-containing side chain in the backbone of polymaleimide. Originally, Toluene and Methyl Ethyl Ketone (MEK) were used for film casting solution. However, Tri-Acetyl Cellulose(TAC) film is damaged by MEK solution. Therefore, we replaced the solvents MEK of film casting solution with PGMEA and observed the photoalignment properties on TAC film. |
