Abstract
Provided is a liquid crystal (LC) device and method thereof. The device comprises (i) a body of liquid crystal, (ii) a first layer comprising a first material, and (iii) a second layer comprising a second material; wherein the first layer is located between the body of liquid crystal and the second layer; the first layer alone aligns the liquid crystal in a first orientation; the second layer alone aligns the liquid crystal in a second orientation; and the first orientation is different from the second orientation. With optimized first layer thickness, the invention can be used in sensor applications to improve detection sensitivity, and in LCD applications with enhanced control over LC pretilt transition.
