碩士 === 中原大學 === 應用物理研究所 === 97 === Abstract Liquid crystal display (LCD) is severely requested on the market, and MVA mode is valued because it’s high contrast. But it has serious color washout in the off axis of MVA mode in the off axis. In this thesis we analyze the color washout of MVA mode and compare the various definition of the color washout nowadays and propose a new value to depict color washout phenomenon (G value). To analyze the influence of LC’s domains, optical structure and cell gap on color washout in MVA mode by using G value and 1D LCD MASTER. We find the optimum design with 8-domain MVA technique to improving color washout. Finally, we use new driving method for iMVA panel to verify the optimization searched by using G value of 8-domain technique.
