Formation of Surface Microstructure Arrays by Selective Wettability for Wide-Viewing Liquid Crystal Displays

Abstract

We developed a simple and powerful method of fabricating surface microstructure arrays for wide-viewing liquid crystal (LC) displays on the basis of the selective wettability. The surface microstructures are spontaneously formed on both the top and bottom substrates by selectively patterning the corresponding wettability commanding layers. An axially symmetric director configuration is generated by the electric-field distortions around each surface microstructure in the field-on state. Our LC cell having the surface microstructures shows good electro-optic properties and wide-viewing characteristics.
