Electro-Optic Characteristics Of Fringe-Field Driven Transflective Lcd With Dual Cell Gap

We have fabricated transflective liquid crystal (LC) cell with dual cell gap driven by fringe field using a nematic LC with positive dielectric anisotropy and studied electro-optic characteristics of the cell. Reflective part consists of a polarizer and lambda/2 compensation film and LC cell with retardation value of lambda/4. Transmissive part is composed of two lambda/2 compensation films, LC cell with lambda/2, and two parallel polarizers. This LC cell with optimized cell parameters shows low wavelength dispersion, low power consumption and contrast ratio greater than 5 in polar angles of over 50 degrees in all directions and over 80 degrees in certain azimuthal cross-sectional planes in the reflective and transmissive parts.
