A uniform alignment of the liquid crystals (LCs) is needed in high-quality liquid crystal display devices. In general, polyimide has been used for initial vertical alignment of LCs because it provides better uniformity and stability than other materials. However, this alignment process needs additional multi-step process for thin film formation before injecting liquid crystals, resulting in long processing time and high manufacturing cost. For this reason, we were interested in self-alignment of LCs using novel functional organic materials instead of polyimide layer. In this study, we proposed a new alignment methodology for LCD device using the nanoscale self-assembled molecular layer formed by hydrogen bonding. This method offers a facile manufacturing process involving simple doping of alignment agent in LC medium and provides various functionalities to advanced LCD. |
