This paper reports photoalignment control of discotic liquid crystal (DLC), a pentakis-(phenylethynyl)benzene derivative, using a thin film of an azobenzene-containing polymer. The polymer films was irradiated with non-polarized light obliquely, subsequently annealed at 240°C and coated with a DLC solution to give a mono-domain texture of DLC films with excellent optical quality. Photopatteming of DLC films was achieved by imagewise irradiation of the polymer film at an oblique incident.
