  The present invention provides a compound represented by formula (i), a liquid crystal composition using the compound, and a liquid crystal display device using the liquid crystal composition. The compound represented by formula (i) has a partial structure K i1 represented by any of general formulas (K-1) to (K-17) and further has ring B having at least two P-Sp- groups. Therefore, when used for a liquid crystal composition, the compound adsorbs to substrates sandwiching the liquid crystal composition (liquid crystal layer) and allows liquid crystal molecules to be held such that they are aligned in a vertical direction without a PI layer, and improved alignment stability and low-temperature storage stability can be achieved.

  本发明提供了一种由式（i）表示的化合物，使用该化合物的液晶组合物，以及使用该液晶组合物的液晶显示装置。式（i）表示的化合物具有由一般式（K-1）至（K-17）中的任何一个表示的部分结构Ki1，并且进一步具有至少两个P-Sp-基团的环B。因此，当用于液晶组合物时，该化合物吸附到夹持液晶组合物（液晶层）的基板上，并允许液晶分子被保持，使它们在垂直方向上对齐而无需PI层，并且可以实现改善的对齐稳定性和低温储存稳定性。

  The present invention provides a liquid crystal display device that allows a reduction in a voltage holding ratio (VHR) of a liquid crystal layer and an increase in an ion density (ID) in the liquid crystal layer to be suppressed and thereby addresses issues of faulty display such as white missing pixels, alignment inconsistencies, and burn-in. The liquid crystal display device according to the present invention, having a feature of suppressing the reduction in a voltage holding ratio (VHR) and the increase in an ion density (ID) in a liquid crystal layer and thereby suppressing occurrence of faulty display such as burn-in, is particularly useful as VA-mode and PSVA-mode liquid crystal display devices for active-matrix driving and may be used for liquid crystal display devices such as a liquid crystal TV, a monitor, a mobile phone, and a smart phone.

  本发明提供了一种液晶显示装置，可以减少液晶层的电压保持比（VHR）并抑制离子密度（ID）的增加，从而解决白色漏失像素、对准不一致和烧屏等显示故障的问题。本发明的液晶显示装置具有抑制液晶层电压保持比（VHR）降低和离子密度（ID）增加的特点，从而抑制烧屏等显示故障的发生，特别适用于主动矩阵驱动的VA模式和PSVA模式液晶显示装置，并可用于液晶电视、显示器、手机和智能手机等液晶显示装置。
