Abstract
The present invention relates to a liquid crystal composition, which is a liquid crystal composition containing a compound represented by General Formula (II-1) as an anti-oxidizing agent for a liquid crystal composition containing the compound represented by General Formula (II-1) and also as a first component, and a compound represented by General Formula (K) as a second component. The compound represented by General Formula (II-1) enables obtainment of a working effect of the anti-oxidizing agent, and therefore it allows provision of a liquid crystal composition containing the anti-oxidizing agent which has improved reliability like low temperature stability, while the high dielectric anisotropy is maintained.
