<p>A liquid crystal composition is provided that satisfies many characteristics among the characteristics such as a high maximum temperature of a nematic phase, a low minimum temperature of a nematic phase, a small viscosity, a large optical anisotropy, a large negative dielectric anisotropy, a large specific resistance, a high stability to ultraviolet light and a high stability to heat, or that is properly balanced regarding many characteristics. The liquid crystal composition has a negative dielectric anisotropy and includes two components, wherein the first component is at least one compound selected from the group of compounds represented by formulas (1-1) and (1-2), and the second component is at least one compound selected from the group of compounds represented by formula (2):
wherein, for example, R 1 , R 2 , R 3 and R 4 are each alkyl having 1 to 12 carbons; Z 1 , Z 2 and Z 3 are each a single bond or - (CH 2 ) 2 -; and ring A is 1,4-cyclohexylene or 1,4-phenylene.</p> |
