Abstract

The invention discloses a color filter and a manufacturing method thereof. The color filter includes a first black matrix (black matrix) and a second black matrix arranged on the substrate, wherein each second black matrix is ​​located between any two adjacent first black matrices, and the first black matrix is ​​used to define complex numbers sub-pixel intervals, and the second black matrices are respectively located in the sub-pixel intervals. The color layer is arranged in the sub-pixel interval, and part of the color layer is located on the second black matrix to form an alignment bump.

Description

technical field [0001] The present invention relates to a color filter and a manufacturing method thereof, in particular to a color filter with improved panel light leakage and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (LCD) is a kind of flat panel display, and it is widely used in various electronic products due to its advantages of small size, light weight, thin thickness, and low power consumption. Therefore, the demand for liquid crystal displays is gradually increasing, and the quality of display effect of consumers is also increasing accordingly. [0003] A liquid crystal display is mainly formed by laminating a pair of substrates, and the middle of the two substrates is filled with liquid crystal molecules. Corresponding electrodes are respectively formed on the two substrates, which can generate an electric field to adjust the arrangement direction of the liquid crystal molecules, and then change the polarization direction ...
