Metal dot color optical filter, manufacturing method thereof and liquid crystal display device

Abstract

The invention relates to a metal dot color optical filter, a manufacturing method thereof and a liquid crystal display device. The metal dot color optical filter comprises a green light metal dot material with a fluorescence peak close to 530 nanometers or a red light metal dot material with a fluorescence peak close to 635 nanometers, wherein the particle size of the green light metal dot material and the particle size of the red light metal dot material are less than 2 nanometers. The manufacturing method of the metal dot color optical filter comprises the steps of: step 10, preparing the green light metal dot material; step 20, preparing the red light metal dot material; and step 30, preparing the metal dot optical filters by using the green light metal dot material and the red light metal dot material respectively. The liquid crystal display device comprises the metal dot color optical filter. The metal dot material adopted by the metal dot color optical filter has a quantum size effect, and the light color is simple to adjust; the adopted metal dot material has good solubility and can be prepared into ink; and the adopted metal dot material is simple to synthesize, free of toxic elements such as lead and cadmium, environmentally friendly, low in cost and suitable for commercial application.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a metal dot color filter, a manufacturing method thereof, and a liquid crystal display device. Background technique [0002] Liquid crystal displays have excellent performance, good mass production characteristics, high degree of automation, low cost of raw materials, and broad development space. They will quickly become mainstream products in the new century and a bright spot of global economic growth in the 21st century. Most of the liquid crystal displays are backlight liquid crystal displays, which are composed of a liquid crystal panel and a backlight module. A general liquid crystal panel includes a color filter substrate and a thin film transistor array substrate. [0003] The liquid crystal panel itself does not emit light, so its color reproduction capability is realized through a color filter (color filter, CF). The traditional color photoresist adopts the pigment di...
