The present invention provides a polymerizable liquid crystal composition capable of forming a uniform homeotropic alignment in producing a polymer through polymerization of the polymerizable liquid crystal composition. Further, the present invention provides a polymer obtained through polymerization of the polymerizable liquid crystal composition and having good alignment performance and high durability (retardation retention) with little cissing, and an optically anisotropic body using the polymer. Specifically, the present invention provides a polymerizable liquid crystal composition containing a polymerizable liquid crystal compound represented by the general formula (II-1), one or more kinds of polymerizable liquid crystal compounds (II-2) having one polymerizable functional group and/or one or more kinds of polymerizable liquid crystal compounds having 2 or more polymerizable functional groups in the molecule and represented by the general formula (I-1).

Provided are a liquid crystal composition satisfying at least one of characteristics such as high maximum temperature, low minimum temperature, small viscosity, suitable optical anisotropy and large dielectric anisotropy, or having a suitable balance regarding at least two of the characteristics, and an AM device including the composition.

The liquid crystal composition contains a quencher as a first additive, and may contain a specific compound having large negative dielectric anisotropy as a first component, a specific compound having high maximum temperature or small viscosity as a second component, or a specific compound having a polymerizable group as a second additive.
