Title:
COMPOUND, LIQUID CRYSTAL COMPOSITION AND HIGH-FREQUENCY PHASE SHIFTER
Document Type and Number:
WIPO Patent Application WO/2022/198557
Kind Code:
A1
Abstract:
Providing a compound represented by the general formula (I), which contains, in its structure, a thieno [3, 2-b] thiophene-2, 5-diyl group having a sulfur atom bonded at the 2-position; and providing a liquid crystal composition containing the compound and a device using the liquid crystal composition. The disclosed compound has a large refractive index anisotropy Δn and a high compatibility with a liquid crystal composition, and exhibits a large dielectric constant anisotropy in a high frequency region; and therefore, it is useful as a material for a device of a high-frequency phase shifter, a phased array antenna, an image recognition device, distance measuring equipment, a liquid crystal display device, a liquid crystal lens, a birefringent lens for stereoscopic image display, or the like.
