  Provided are a compound represented by general formula (I), a liquid crystal composition that uses the compound, and a liquid crystal display device that uses the liquid crystal composition. Adding the compound represented by general formula (I) to a liquid crystal composition can prevent degradation of the liquid crystal composition by light, heat, etc. The compound represented by general formula (I) dissolves well in the liquid crystal composition. Thus, when the compound represented by general formula (I) is used, a liquid crystal composition having both low viscosity (η) and high reliability can be prepared, and a high-speed response liquid crystal display device can be provided.

  提供了一个通式（I）表示的化合物，使用该化合物的液晶组合物，以及使用该液晶组合物的液晶显示装置。将通式（I）表示的化合物添加到液晶组合物中可以防止光、热等因素对液晶组合物的降解。通式（I）表示的化合物在液晶组合物中溶解良好。因此，当使用通式（I）表示的化合物时，可以制备具有低粘度（η）和高可靠性的液晶组合物，并提供高速响应的液晶显示装置。
