Thesis liquid crystals
Senior thesis abstract it has long been recognized that a non-contact alignment method is essential for the production of high resolution liquid crystal displays current methods of liquid crystal alignment utilized in the making of commercial lcd’s involve rubbing a. Liquid crystal, placed between a polarizer and a mirror, changes birefringence, which causes a change in the reflectivity of the system the aim of the thesis is to analyze these different mechanisms. While liquid crystals are today widely known for their successful application in flat panel displays (lcds), academic liquid crystal research is more and more targeting situations where these anisotropic fluids are put to completely different use, in varying contexts.
- The importance of soft matter research, as a major class of materials including liquid crystals, polymers, colloids, emulsions, and forms, is attributed to the behavior resemblances in each branch of soft matter responding.

The foregoing thesis entitled “electro-optic studies on chiral liquid crystals”, is hereby approved as a creditable study of research topic and has been presented in satisfactory manner to warrant its. The present thesis deals with extensive and systematic investigations based on structural, dielectric, and photonic studies of thermotropic nematic (uniaxial and biaxial) and ferroelectric liquid crystals (conventional and de vries) to explore their basic and applied aspects. Lyotropic liquid crystals are usually formed from water and one or two surfactants and possibly oils within a definite concentration and temperature range [9-11] in the lyotropic. The ferroelectric liquid crystal displays normally suffers from less contrast ratio and vision angle to produce high optical contrast and colours in flc displays, guest-host mode is widely used.
