Embodiment Construction

[0019] see image 3 , is a schematic diagram of the first embodiment of the color filter of the present invention. The color filter 30 includes a first base layer 34, a black matrix 33 and a colored layer 32, the first base layer 34 is transparent glass, the black matrix 33 includes an anti-reflection layer 332 and a light shielding layer 333, wherein, The anti-reflection layer 332 includes a first film layer 3321 and a second film layer 3322, the second film layer 3322 and the first film layer 3321 are sequentially arranged on the first base layer 34, and the refractive index of the second film layer 3322 is less than The refractive index of the first film layer 3321. The second film layer 3322 is mainly composed of chromium oxide (CrO X , X is the ratio of O to Cr) material, and its thickness is 20-60nm; The first film layer 3321 is mainly made of chromium nitride (CrN Y , Y is the ratio of N to Cr) material, and its thickness is 20-100nm. The light-shielding layer 333 i...

Abstract

The present invention relates to color optical filter and LCD device therewith. The color optical filter includes one first substrate, and one black matrix and coloring layer. The black matrix layer includes one anti-reflecting layer and one mask layer set on the first substrate layer successively; the coloring layer and the black matrix layer are set on the first substrate alternately; and the coloring layer covers the surface of the mask layer.

Description

【Technical field】 [0001] The invention relates to a color filter and a liquid crystal display device using the color filter. 【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 23 is arranged b...
