    Abstract: “Object” To provide a tilt-imparted liquid crystal display element that is obtained through UV irradiation of a polymerizable liquid crystal composition, whose drive voltage can be reduced with a fast decay time maintained, and that is well balanced between characteristics, such as decay time, drive voltage, and transmittance. A polymerizable liquid crystal composition for use in it is also provided. “Solution” A liquid crystal display element has polymer networks formed in the liquid crystal phase 5 in FIG. 3. The polymer networks are formed by polymerizing a polymerizable liquid crystal composition that contains, as essential ingredients, a radically polymerizable monomer component (A), a liquid crystal material (B), and a polymerization initiator (C) that has a molecular structure resulting from substituting any two or more hydrogen atoms in the aromatic nucleus in the molecular structure of an alkylphenone-based photopolymerization initiator, for example with a C1-10 alkyl group (i).

    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.
