The photo-alignment layer is realized based on a two-step irradiation to first achieve molecule alignment to form the photo-alignment layer and then stabilize this layer. To realize the photo-alignment layer, a pre-determined surface of the substrate is first coated with a film of mixture. The mixture comprises an azo dye and a monomer preferably mixed in an optimal concentration of 0.67 wt/wt. The azo dye and the monomer have light-absorption peaks at different wavelengths such that photo-alignment of the azo-dye molecules and stabilization of the photo-alignment layer by polymerization of the monomer are achievable by two separate exposures of light to the film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stabilized photo-alignment layer for liquid crystal","description":"A liquid-crystal photo-alignment layer that is composed of polymer stabilized azo dyes is provided, where a polymer network is introduced in the photo-alignment layer for stabilization.
