In this study, we evaluated the electro-optical characteristics and structural stability in curved state of dye-doped liquid crystal (LC) gel film for stretchable displays. As the results, maximum contrast ratio of 6.7:1 and suppression of LC flow were achieved by optimum of blend condition such as gelator and dye concentration.

In this study, we examined the mechanical durability and self-recovery characterization of liquid crystal gel films with lysine-based gelator. The results indicated that the structural destruction in liquid crystal gel films is attributed to dissociation among network structure. The cracked LC gel films can be recovered by formation of sol-sate films.
