Embodiment 1～6 and comparative example 1～9

[0543] As Examples and Comparative Examples, the following polymerizable compound-containing liquid crystal compositions (hereinafter also referred to as polymerizable liquid crystal compositions) were prepared. Each polymerizable liquid crystal composition contains each liquid crystal composition described in Table 2, each polymerizable compound, and an antioxidant as the case may be. As for the polymerizable compound, the polymerizable compound represented by the above formula was added in proportions (% by mass) shown in the table with respect to the liquid crystal composition (excluding the polymerizable compound and the antioxidant). The addition amount of antioxidant was 0.005 mass % with respect to the liquid crystal composition.

Abstract

The present invention provides a polymerizable compound-containing liquid crystal composition containing a compound represented by general formula (i) and two or more polymerizable compounds represented by general formula (P), and provides a liquid crystal display element using the polymerizable compound-containing liquid crystal composition.

Description

technical field [0001] The present invention relates to a liquid crystal composition containing a polymerizable compound useful as a liquid crystal display material, and a liquid crystal display element using the same. Background technique [0002] PSA (Polymer Sustained Alignment) type and PSVA (Polymer Sustained Vertical Alignment) type liquid crystal TV as a liquid crystal display element using a liquid crystal composition with a negative dielectric constant anisotropy Δε , liquid crystal monitors, etc. are spreading, and Patent Documents 1 to 5 disclose various polymerizable compounds and liquid crystal compositions containing the same as liquid crystal compositions suitable for these applications. [0003] However, the properties of the conventional liquid crystal composition containing a polymerizable compound are still insufficient for high-definition liquid crystal TVs called 4K and 8K. Specifically, 4K and 8K liquid crystal display elements must be high-definition ...
