Abstract

Liquid crystal displays (LCDs) are used for displaying still and moving images in all types of large or small display media, including monitors for laptop computers or desktop personal computers, display panels for TVs, mobile phones, smartphones, on-board navigation, viewfinders for video cameras, preview screens for digital cameras, projection displays and information display monitors in public spaces. In order to utilize liquid crystal (LC) material in LCDs for such applications, an electro-optical response is applied, in which the transmitted light intensity is controlled by the application of a set voltage to the driver devices. For this purpose, the alignment control of LC molecules is essential. In this chapter, alignment materials and their surface deformation anisotropy for alignment control of LC molecules are discussed.
