| 摘要 | A liquid crystal composition includes a nematic liquid crystal, and a compound of Formula (I) where R is an alkyl, aryl, aralkyl or heteroaryl having 6 to 30 carbon atoms, wherein the compound accounts for 0.3 to 0.6% of the liquid crystal composition. Further, a sensing device includes a substrate, a frame, an alignment film, the liquid crystal composition as described above, and two polarizers. The frame is connected to the substrate and forms an accommodation space having an opening, and the alignment film and the liquid crystal composition are both located inside the accommodation space. One of the polarizers is arranged in correspondence with the opening such that a channel exists between the polarizer and the frame, the other polarizer is located at a lateral side of the substrate, and the polarization directions of the two polarizers intersect with each other. | ||||||
