Micro deflection (MD) LCD modes have been investigated. Zigzag shaped electrodes patterned on each side of substrates are faced in parallel. Initial aligned OFF state of nematic liquid crystal molecules due to rubbed or coated surface effect. The second ON state in which liquid crystal molecules are inclined 45 degrees from the cell surface and also 45 degrees twisted from the initial azimuthal direction due to obliquely applied electric field. Initially alignments are selected to be homogeneous, homeotropic and twisted states. Contrast ratio (CR) of transmitted light was measured for nine combinations of polarizers and analyzers. Contrast ratio was 462:1 for homogeneous alignment, parallel nicols under He-Ne laser illumination. Rise and fall times were 23ms and 294ms, respectively. Contrast ratio of over 100:1 was obtained for whole azimuthal direction at viewing angle of below 40 degrees.
