  • Patent number: 9442321
    Abstract: There is provided a liquid crystal display apparatus that may limit a reduction in the voltage holding ratio (VHR) of a liquid crystal layer and limit an increase in the ion density (ID) in the liquid crystal layer and address issues of faulty display such as white missing pixels, alignment inconsistencies, and burn-in. The liquid crystal display apparatus includes a first substrate, a second substrate, a liquid crystal composition layer held between the first substrate and the second substrate, a color filter including a black matrix and at least RGB three-color pixel portions, a pixel electrode, and a common electrode. The liquid crystal composition layer is composed of a liquid crystal composition including one or more compounds represented by General Formula (LC1).
