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。
