Abstract
The ferroelectric liquid crystal materials are a kind of materials with great potential in liquid crystal (LC) material field. The property of fast switching time makes them to have great application in liquid crystal display. To understand their arrangement structure is the most fundamental and important thing. As we know the arrangement structure of a LC material, we can further make it for applications in LCD industry or academic research. Conoscope is a good method for this purpose. By analyzing the interference patterns of LCs, we can identify the molecular arrangement structure of LC materials.
The main research purpose in this thesis is to observe unknown phase liquid crystal materials by conoscope. We get two materials with unknown phase. By analyzing the interference patterns of them, we try to identify the phase at various temperatures. The results of our experiment show that the conoscope is really a good method for phase identification and the materials we observed are ferroelectric liquid crystal materials.
