We demonstrate uniformly and unidirectionally distributed pretilt characteristics of a liquid crystal cell fabricated via substrate with scan-directional slant nanosized surface groove pattern driven through an atomic force microscopic (AFM) tip that is continuously modulating the contact in scanning line direction. The resultant electro-optic (LC) made by our advanced AFM lithography technique show it generates unidirectional guarantees wider LC applications.
