Stability‐enhanced liquid crystal mode for flexible display applications

Abstract We demonstrated stability‐enhanced liquid crystal (LC) displays using pixel‐isolated LC mode in which LC molecules are isolated in pixel by horizontal polymer layer and vertical polymer wall. The device shows good electro‐optic properties against external point or bending pressure due to the polymer structures. The polymer wall acts as supporting structure from mechanical pressure and prevents the cell gap from bending. Moreover, the polymer layer acts as an adhesive to ensure a tight attachment of the two substrates. We present herein various methods for producing polymer structures by using an anisotropic phase separation from LC and polymer composites or patterned micro‐structures for stable flexible liquid crystal displays.
