Embodiment Construction

[0022] see image 3 , is a schematic structural diagram of the first embodiment of the black matrix of the present invention. The black matrix 33 includes a first anti-reflection layer 332, a light-shielding layer 333 and a second anti-reflection layer 334, the first anti-reflection layer 332, the light-shielding layer 333 and the second anti-reflection layer 334 are sequentially arranged on a first On a base layer 34, wherein, the first anti-reflection layer 332 includes a first film layer 3321 and a second film layer 3322 which are successively arranged on the first base layer 34, and the refractive index of the second film layer 3322 is greater than that of the first film layer The refractive index of layer 3321. The first film layer 3321 is mainly composed of chromium oxide (CrO X , X is the atomic number ratio of O and Cr) material, and its thickness is 20-60nm; the second film layer 3322 is mainly made of chromium nitride (CrN Y , Y is the atomic number ratio of N and...

Abstract

The present invention relates to a kind of black matrix, color optical filter and LCD device with the black matrix. The black matrix includes the first anti-reflecting layer, one mask layer and the second anti-reflecting layer set successively, and the second anti-reflecting layer includes at least one chromium monoxide or chromium nitride film.

Description

【Technical field】 [0001] The invention relates to a black matrix, a color filter using the black matrix 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 structural schematic diagram of a color filter in the prior art. The color filter 20 includes a glass substrate 24 , a black matrix 23 , a colored layer 22 and an ITO (Indium Tin Oxide) layer 21 . The colored layer 22 has three colored units of red (R), blue (B), and green (G), and the three colored units are repeatedly and regularly arranged on the glass substrate 24 to pass through the three primary colors of red, blue, and green light respectively, and block Light of other wavelengths passes through. The black matrix ...
