Embodiment Construction

[0028] see image 3 , is a schematic diagram of the structure of the black matrix of the present invention. The black matrix 33 includes a first anti-reflection layer 331 and a second anti-reflection layer 332, the first anti-reflection layer 331 and the second anti-reflection layer 332 are sequentially disposed on the first base layer 34, wherein the second anti-reflection layer An anti-reflection layer 331 includes a first film layer 3311 disposed on the first base layer 34 and a second film layer 3312 thereon. The refractive index of the first film layer 3311 is smaller than that of the second film layer 3312 . The first film layer 3311 is mainly composed of chromium oxide (CrO X ) material with a thickness of 20-60nm; the second film layer 3312 is mainly made of chromium nitride (CrN Y ) material, and its thickness is 20-100nm.

[0029] The second anti-reflection layer 332 is the same as the first anti-reflection layer 331, which includes a third film layer 3321 and a f...

Abstract

The black matrix includes at least two identical stacked anti reflection layers. Each anti-reflection layer includes first film and second film having different refractive indexes. The said first film and second film are stacked. The black matrix and color filter and liquid crystal display device utilizing the black matrix possess higher optical performances.

Description

【Technical field】 [0001] The invention relates to a black matrix, a color filter and a liquid crystal display device. 【Background technique】 [0002] Liquid crystal display is a passive display device. In order to achieve the effect of color display, a color filter needs to be provided for it. Its function is to provide color for the liquid crystal display. components to display different color images. [0003] see figure 1 , is a schematic diagram of a prior art liquid crystal display device. The liquid crystal display device 100 includes a first base layer 14 and a second base layer 17 filled with a liquid crystal layer 15 . The bottom surface of the second base layer 17 includes a TFT array 16 . The first base layer 14 and the coloring layer 12 thereon, the black matrix 13 and the ITO (Indium Tin Oxide, indium tin oxide) layer 11 together constitute a color filter (not shown). The black matrix 13 is distributed in rows and columns on the first base layer 14 to form m...
