Abstract
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.
