Abstract
In this thesis, we use fringe-field as the major drived method to producing FFS LC mode. This kind of LCD has wide viewing angle and good electro-optic efficiency. At first, according to wide-band theory, we can design the hybrid aligned reflective LCD which have wide-band effect. Then, we discuss the influences of parameters on E-O curve. Secondly, we design two different transmissive structures in the light of the same concept : parallel aligned and hybrid aligned transmissive structures. By using the 2DIMMOS software, we fine tune the related parameters of reflective or transmissive region in order to improve the inconsistence of E-O curve. According to the result of calculation with theory, we add positive C plates to compensate the retarder and LC layer by the software TechWiz LCD. After a series of simulations and corrections, we can finally devise a transflective LCD which is TR matched and with wide-viewing angle property.
