Subject
The subject is to provide a liquid crystal composition that includes a polymerizable compound (or polymer) and a polar compound, where the homeotropic alignment of liquid crystal molecules can be achieved by the action of these compounds, and a liquid crystal display device including this composition. This composition satisfies at least one of characteristics such as a high maximum temperature, a low minimum temperature, a small viscosity, a suitable optical anisotropy, a large positive dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light or heat or a large elastic constant, or is suitably balanced regarding at least two of the characteristics.
The means concerns a nematic liquid crystal composition that has positive dielectric anisotropy and that includes a polymerizable compound as an first additive and a polar compound as a second additive, and the composition may include a specific liquid crystal compound having a large positive dielectric anisotropy and a specific liquid crystal compound having a high maximum temperature or a small viscosity, and concerns a liquid crystal display device including the composition.
