Liquid crystal display device

Abstract

This invention relates to a liquid crystal display device using a color filter which uses a specific liquid crystal composition and a specific pigment. The present invention provides a liquid crystal display device which prevents decreases in voltage holding ratio (VHR) of a liquid crystal layer and increases in ion density (ID), and solves the problem of display defects such as white spots, uneven alignment, and burn-in. This liquid crystal display device is characterized by preventing decreases in the voltage holding ratio (VHR) of a liquid crystal layer and increases in ion density (ID), and by suppressing the occurrence of display defects such as burn-in, and in particular is useful in VA-mode and PSVA-mode liquid crystal display devices for active matrix driving, and can be applied in liquid crystal display devices such as liquid crystal TVs, monitors, mobile phones and smart phones.

Description

Technical field

[0001] The present invention relates to a liquid crystal display device. Background technique

[0002] Starting from clocks and calculators, liquid crystal display devices have been used in various household electrical appliances, measuring equipment, automotive panels, word processors, electronic notebooks, printers, computers, and televisions. As a liquid crystal display method, the representative liquid crystal display method can include TN (twisted nematic) type, STN (super twisted nematic) type, DS (dynamic light scattering) type, GH (guest-host) type, IPS (plane switching) Type, OCB (optical compensation birefringence) type, ECB (voltage controlled birefringence) type, VA (vertical orientation) type, CSH (color super vertical) type or FLC (ferroelectric liquid crystal), etc. In addition, as a driving method, the conventional method has evolved from static driving to multiplex driving. The simple matrix method and the recent active matrix (AM) method using T...
