Abstract

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.

Claims (8)

1. A compound represented by the formula (I-b)

wherein in the formula, R H3 , R H4 , and R H5 are each independently a hydrogen atom, and n H1 and n H2 each independently represent an integer of 1 to 4.

2. A composition comprising one or two or more of the compounds according to claim 1 .

3. The composition according to claim 2 , wherein the composition exhibits a liquid crystal phase at room temperature.

4. A liquid crystal display device, comprising the composition according to claim 2 .

5. The compound according to claim 1 , wherein the compound is represented by the formula (I-1) or (I-2),

R 11 , R 12 , and R 13 are each independently a hydrogen atom.

6. The composition according to claim 3 , wherein the compound can be dissolved completely at 500 ppm into the composition.
