Liquid crystal photo‐alignment using azo‐dyes for display and photonics applications is discussed. Various types of the glass and plastic substrates are used. Special types of 3D LC alignment, LC alignment inside thin micro tubes, and LC cladding layers in Si based waveguides and grating surface are concerned. The azo‐dye photoalignment of polymerized LC films used as optical elements, such as polarizers and phase retarders is also considered. Optically rewritable liquid crystal display for plastic cards applications is shown.
