We present a multi-layer composite thin-film polarizer combining light-stable LCP-M10 and photo-aligned azo dye films to enhance photostability. The design reduces photodegradation while preserving high dichroic performance, demonstrating superior long-term stability in optical tests. This approach offers durable, high-performance solutions for display systems.
