Used primarily in liquid crystal displays (LCDs), this compound functions as a key component in nematic liquid crystal mixtures. Its long alkyl chain and cyano group contribute to stable mesophase behavior over a broad temperature range, making it suitable for display applications requiring consistent performance under varying conditions. It helps achieve desired dielectric anisotropy and low viscosity, which are critical for fast switching times and energy-efficient operation in LCD devices. Commonly found in mixtures for twisted nematic (TN) and super twisted nematic (STN) displays, it supports clear image reproduction and improved response times.
