Provided is a curable composition. The curable composition, which may provide an encapsulating material, of which processibility and workability before curing are effectively maintained and which has excellent light transmissivity, light extraction efficiency, hardness, crack resistance, adhesion strength and thermal shock resistance after curing, is provided. Further, the curable composition may show effectively controlled tackiness in the surface and may not show whitening under the high temperature or high humidity condition before or after curing.

Curable composition

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 (&#x2212;) 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 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.
