Cellulose Nanocrystals as an Alignment Layer for Liquid-Crystal Displays in a Circular Economy

Student

Description:

We report a Liquid Crystal Display (LCD) structure employing cellulose nanocrystals (CNC) as a recyclable, non-toxic alignment layer in a twisted nematic configuration. Fabricated via spin coating and mechanical rubbing, the CNC alignment layer demonstrated comparable performance to polyimide in transparency, threshold voltage, response speed, and liquid crystal alignment. This work demonstrates the viability of CNC alignment layers, advancing LCD technology toward circular economy principles.
