摘要:
Disclosed is a novel radially multi-branched polymer. The radially multi-branched polymer includes a central molecule to which side-branches are bonded in at least three positions and has an average molecular weight of 500 to 100,000, the side-branch being selected from the group consisting of a polyalkylene oxide, a polyacrylate, a polyester, a polyamide and derivatives thereof. The radially multi-branched polymer is used for manufacturing a low dielectric insulating film to provide a low dielectric insulating film having easily controllable micropores.

摘要:
Disclosed are a silicon-containing compound, a liquid crystal composition comprising the same compound, and a liquid crystal display device comprising a liquid crystal layer prepared from the liquid crystal composition. The silicon-containing compound, which forms the liquid crystal composition, has low viscosity and high positive dielectric anisotropy. Therefore, it is possible to provide a liquid crystal display device, which has a fast response time and can be driven at a low voltage.

Disclosed are a silicon-containing compound, a liquid crystal composition comprising the same compound, and a liquid crystal display device comprising a liquid crystal layer prepared from the liquid crystal composition. The silicon-containing compound, which forms the liquid crystal composition, has low viscosity and high negative (−) dielectric anisotropy. Therefore, it is possible to provide a liquid crystal display device, which has a fast response time and can be driven at a low voltage.

Disclosed are a vinylsulfone derivative, a liquid crystal composition comprising the same, and a compensation film for a liquid crystal display device using the same liquid crystal composition. More particularly, the vinylsulfone derivative is a liquid crystal material of a high-quality view angle compensation film, which improves a contrast ratio measured at a tilt angle when compared to a contrast ratio measured from the front surface and minimizes color variations in a black state depending on view angles.
