Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the color filter 20 provided by the embodiment of the present invention includes a substrate 10 , a black matrix 11 , a colored layer 12 located between the black matrix 11 , a protection layer 13 and a conductive layer 14 .

[0014] The substrate 10 is usually a transparent substrate, such as a glass substrate.

[0015] The thickness of the black matrix 11 is 800nm ​​to 1000nm, and it is mainly composed of nitride, and the nitride contains chromium, titanium and aluminum.

[0016] The nitride is chromium nitride, titanium nitride, aluminum nitride, titanium aluminum nitride or Ti a Al b Cr c N d , wherein, a:b:c:d is the ratio of atomic number among titanium element, aluminum element, chromium element and nitrogen element.

[0017] Since the probability of chromium, aluminum, titanium and nitrogen to form compounds dec...

Abstract

The invention relates to a color filter which comprises a substrate and a black matrix arranged on the substrate, wherein the black matrix mainly consists of nitrides comprising chromium, titanium and aluminum.

Description

technical field [0001] The invention relates to a color filter and a manufacturing method of the color filter. Background technique [0002] Liquid crystal display (LCD) is widely used in personal computers, televisions and other fields due to its excellent picture quality, external size and low power consumption. In recent years, the LCD industry has developed rapidly and continues to develop in the direction of high precision and large screen . In color LCD products, color filters are essential components. [0003] LCD is a non-active light-emitting element. Its color display must be provided by its own light source device or external ambient light. The grayscale display is formed through the driver and controller, and then the color filter is used to generate red (Red) and green (Green). , Blue (Blue) three primary colors, based on the principle of color mixing to form a color display screen. [0004] A color filter generally consists of a glass substrate, a black matr...
