Characterization of a homeotropic 4-domain liquid crystal cell which uses oblique electric field
Homeotropically aligned liquid crystal (LC) cell with different area electrodes to produce oblique electric field has been fabricated and characterized. Four domain structure is successfully obtained as a simulated result and the LC cell shows wide viewing angle characteristics. Its dynamic process on applying electric field consists of two steps, the fast step where the LC molecules fall down to the substrate and the slow step where the LC molecules change their azimuthal direction. Introducing a black reset pulse which makes the slow process invisible will give favorable effects on both the response speed and motion picture images.
