This composition, which exhibits lyotropic liquid crystallinity, contains: a polymer (P) having an acidic functional group; water; and a compound (A) that is at least one selected from the group consisting of a basic monomer and a base-generating agent. The composition contains: a polymer (P) having a partial structure shown in formula (0); water; and a compound (A) that is at least one selected from the group consisting of a basic monomer and a base-generating agent. Formula (0) has at least one acidic functional group.

A liquid crystal composition includes at least one compound of general Formula I, at least one compound of general Formula II and at least one compound of general Formula M. The polymerizable liquid crystal composition provides a higher VHR (especially an excellent VHR after UV irradiation), a lower surface roughness of the polymer layer, a faster polymerization rate, a lower residual amount of the polymerizable compound and a better pretilt angle stability, which enables the production of a liquid crystal display device with a better voltage stability and a faster response speed, and can effectively reduce or prevent the occurrences of problems such as “burn-in”, “image sticking”, “Zara Particle” and “uneven display” in the liquid crystal display device. A liquid crystal display includes the liquid crystal composition.
