Exploring Carbon Nanocellulose as a Novel Alignment Layer in Liquid Crystal Display Technology

This study introduces a novel Liquid Crystal Display (LCD) structure employing carbon nanocellulose as the alignment layer in a twisted nematic configuration, replacing traditional materials such as polyimide. Derived from wood-based fibers, carbon nanocellulose is a sustainable and eco-friendly material noted for its high tensile strength, good transparency, and low birefringence, making it a good candidate for aligning liquid crystals. The LCD cell was fabricated using carbon nanocellulose as the alignment layer through spin coating followed by mechanical rubbing. Following characterization and evaluation demonstrated its functionality, including uniform alignment of liquid crystals and stability under various operating conditions. The results underscore the potential of carbon nanocellulose as a functional alignment layer in LCDs, offer a recyclable and non-toxic alternative to traditional materials, and pave the way for new opportunities in the circular economy of liquid crystal display technology.
