Photoalignment Properties of Photopolymer based on Chlacone Groups for Negative Dispersion Optical Retarder film |
| 초록 |
OLED panels, one of the parts of OLED, have high reflectivity. Therefore, the retarder film is necessary because of these properties. Especially, the negative dispersion retarder film has a constant retardation regardless of wavelength and thus has an ideal compensation properties. The retarder film consists of a liquid crystal layer and alignment layer for arrange liquid crystal. There are methods of arranging liquid crystals such as rubbing and photoalignment process. One of them, the chemical method, photoalignment process is a non-contact method that solves the problem of rubbing process. In this study, we have synthesized the photopolymer based on chalcone moiety and make a casting solution. This casting solution was used to form the photoalignment layer, which arrange the layer of liquid crystal. The liquid crystal layer consists of RM which has a negative dispersion properties. As a result, we successfully demonstrate a retarder film with negative dispersion properties. |
