[PROBLEMS] To reduce the crystallization temperature remarkably compared to the case of mixing homologs while having a similar skeleton structure, excellent compatibility, and the absolute value of negative dielectric anisotropy (Δε). A liquid crystal composition that can be enlarged is provided. A compound having 2 to 4 ring structures between two side chains, wherein one or more ring structures are 2,3-difluorobenzene skeletons, and the two side chains are linked to different ring structures. Liquid crystal composition containing two or more compounds having different positions of 2,3-difluorobenzene skeletons and the same number of ring structures. However, when the number of ring structures is N and the molecular weights of the two side chains are different, the position of the ring structure where the side chains with higher molecular weight are connected is 1, and the position of the ring structure where the side chains with lower molecular weight are connected is N If the two side chains have the same molecular weight, the position of the ring structure to which the side chains are connected is 1, and the side chains are not connected. The position of the ring structure is defined as 2. [Selection figure] None |
