Abstract	Liquid crystals (LCs) are a unique class of materials exhibiting properties between those of conventional liquids and solid crystals, making them indispensable in various technological applications, from displays to photonics, sensing, and beyond. Despite significant advancements, numerous challenges persist in their material design, synthesis, fabrication, and practical implementation. This review comprehensively examines these challenges, including issues related to alignment uniformity, response times, thermal and chemical stability, high operating voltages, and scalability. Drawing from recent literature, we discuss specific hurdles in traditional and emerging applications such as polymer-dispersed LCs (PDLCs), tunable lenses, radio frequency devices, and wearables. Additionally, we highlight opportunities for overcoming these barriers through innovative materials, computational modeling, and interdisciplinary approaches. The aim is to provide a road map for future research to enhance the performance and broaden the applicability of LC-based technologies.
