Abstract

Disclosed is a liquid crystal display device comprising a backlight having an LED and a color filter having color layers of a plurality of colors including a green color layer. The green color layer of the color filter contains a green pigment composed of brominated zinc phthalocyanine, and the dielectric loss tangent of the green color layer at the driving frequency of the liquid crystal displaydevice is not more than 0.02.

Description

technical field [0001] The present invention relates to a liquid crystal display device and a color filter for a liquid crystal display device, and more particularly, to a liquid crystal display device provided with a color filter whose electrical properties of a coloring layer and an overcoat layer do not affect the conversion properties of liquid crystals and the electrical properties of the overcoat layer. The display device has adverse effects and is excellent in color reproducibility. Background technique [0002] Color liquid crystal display devices are rapidly spreading, including television image display devices and computer terminal display devices. The color filter is an indispensable and important component for the color display of such a liquid crystal display device. In recent years, demands for higher image quality of liquid crystal display devices have increased, and various new types of liquid crystal display devices having high viewing angles and high-speed...
