Abstract

The invention discloses a color filter and a preparation method thereof. A color filter according to an embodiment of the present invention includes: a black matrix distributed in a grid shape and having a plurality of hollow areas; and a filter unit located in the hollow areas, wherein the black matrix includes a main body and at least partially covers the main body The light-reducing layer, the main part includes an organic light-shielding material, a plurality of nano-carbon particles are distributed in the light-reducing layer, and some of the nano-carbon particles in the plurality of nano-carbon particles are connected to the main part, so that the interface between the light-reducing layer and the main part Interpenetrate and overlap. According to the color filter of the embodiment of the present invention, the specular reflectance of the black matrix is ​​low, and the display effect is enhanced.

Description

technical field [0001] The invention relates to the display field, in particular to a color filter and a preparation method thereof. Background technique [0002] Flat display devices such as liquid crystal display (Liquid Crystal Display, LCD), organic light emitting diode display (Organic Light Emitting Display, OLED), and display devices using organic diode (Light Emitting Diode, LED) devices have high image quality and low cost. It is widely used in various consumer electronic products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and has become the mainstream of display devices. [0003] The display device can realize display supporting color patterns through various colorization schemes. In some embodiments, colorization is achieved by adding color filters on the light-emitting substrate. However, in the color filter in the prior art, there is usually a problem that the reflectivity of t...
