Abstract:
Provided are a liquid crystal composition that contains a polar compound having a polymerizable group, in which vertical alignment of liquid crystal molecules can be achieved by action of the compound (or polymer), and a liquid crystal display device including the composition. The composition satisfies at least one of characteristics such as high maximum temperature, low minimum temperature, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to ultraviolet light and heat. The composition is a nematic liquid crystal composition that has negative dielectric anisotropy and contains the polar compound as a first additive, and may contain a specific liquid crystal compound having large negative dielectric anisotropy as a first component, a specific liquid crystal compound having high maximum temperature or small viscosity as a second component and a polymerizable compound as a second additive, and the liquid crystal display device includes the composition.
