The present disclosure relates to a high thermal conductive polymer composite, comprising: a liquid crystalline resin comprising a mesogen and at least one linear polymerization reactive group, wherein the liquid crystalline resin is cured with a linear polymerization initiator and includes a molecular structure aligned in at least one direction.

There is provided a liquid crystal composition that exhibits a sufficiently low viscosity (), a sufficiently low rotational viscosity (1), and a large elastic modulus (K.sub.33) without decreasing the refractive index anisotropy (n) and the nematic phase-isotropic liquid phase transition temperature (T.sub.ni) and without increasing the solid phase-nematic phase transition temperature (T.sub.cn). The liquid crystal display element that uses this liquid crystal composition satisfactorily obtains a pretilt angle and has a high voltage holding ratio (VHR) and high-speed response. Thus, a liquid crystal display element that has no or less alignment defects and display defects such as image sticking, and has high display quality and high response speed is obtained.

Disclosed is a liquid crystalline epoxy compound wherein an epoxy group is positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage. Since the liquid crystalline epoxy compound includes an epoxy group positioned at a side chain of the longer direction of a mesogen group and each of the mesogen group and the epoxy group is connected to the center of the molecular structure through a flexible linkage, the interaction between the mesogens in a cured resin product occurs significantly without weakening even after curing, thereby improving the heat conductivity of the resin compound through the active heat transfer between the mesogens.

Provided are a polymerizable composition in which precipitation or the like of crystals does not occur and which has high storage stability; and a polymerizable composition in which unevenness is unlikely to occur when a film-like polymerized material obtained by polymerizing the composition is prepared. Further, provided are an optically anisotropic body, a retardation film, an optical compensation film, an anti-reflective film, a lens, and a lens sheet which are formed of the polymerizable composition, a liquid crystal display element, an organic light-emitting display element, a lighting element, an optical component, a colorant, a security marking, a member for emitting a laser, a polarizing film, a coloring material, and a printed matter for which the polymerizable composition is used.
