Abstract : Sealant for liquid crystal displays (LCD sealant) is one of the most important LC materials. In spite that its quantity in the LCD composition is very low, LCD sealant closely relates to the reliability of devices because LCD sealant is in direct contact with the liquid crystal. In recent years, the more advanced the LCD technology is, the LCD sealant is required to be more sophisticated and diverse. In this paper, we discuss LCD sealants using examples for our epoxy resin type LCD sealant "STRUCTBOND TM". The following topics will be discussed : 1. The application methods. 2. The recent needs and characteristics (stress relaxation technology, adaptability to cell - gap former processes, and recent demand by changing the LCD technology). 3. Future trends (approach for smectic type LCD, sealant for plastic LCD and the sealant for UV curing type).
Keywords : LCD sealant, Stress relaxation, Smectic type LC, Plastic LCD, UV curing type

Abstract : Liquid crystals show optical anisotropy, and exhibit a lot of phase under a polarized microscope. Since each liquid crystalline phase forms characteristic structures and defects, and its textures reflect them, the textures include much information about molecular orientation, layer structures and optical properties of the liquid crystalline phases.
Therefore, microscopic observation is one of the most powerful techniques to investigate liquid crystals. In this paper, various textures of liquid crystalline phases (nematic, SmA, SmC(*), and SmCA()) observed under a polarized microscope are observed, and the relation between the textures and structures are expounded.
Keywords : Texture, Nematic, Smectic, Defect
