Abstract
Devices and method of fabrication a liquid crystal electro-optic device which is based on light scattering and diffraction from a multiple domain field-effect liquid crystal configuration are provided. The multiple domains include random liquid crystal alignment directions fabricated by photo-alignment and have sizes ranging from sub-micrometer to several micrometers. The random alignment in the plane can be of two or more directions whereas the pretilt angle can vary between zero and 90°. The randomness of the planar directions of the liquid crystal director can be generated by a designed photo mask in combination with uniaxial photo-alignment.
