Paragraph 0315; 0316; 0368; 0369, (2020/09/26)
The present invention discloses a novel diamine including benzene rings connected by functional groups on both sides of a p-terphenyl structure in which three benzene rings are connected, and having a structure in which the benzene rings are substituted with various substituents. In addition, the present invention can provide a polyimide film having improved physical properties by including the novel diamine as a polymerization component.COPYRIGHT KIPO 2021
Polymerizable mesogen compound having improved photoreactive efficiency and polymerizable liquid crystal compositions containing the same

, (2016/12/26)
The present invention relates to a polymerizable mesogen compound having improved photo-reaction efficiency by introducing an alpha-thiomethyl acrylate group as a photo-reactive group, and to a polymerizable liquid crystal composition containing the same. The polymerizable mesogen compound of the present invention has improved photo-reaction efficiency at a relatively low energy state by introducing an alpha-thiomethyl acrylate group as a photo-reactive group, retains excellent solubility in a host liquid crystal due to an asymmetric structure thereof, and improves stability of the pretilt angle after photo-crosslinking, and thus can be useful as a polymerizable liquid crystal composition, particularly, a polymerizable liquid crystal composition for a polymer stabilization alignment type liquid crystal display.
