Abstract

The invention relates to a color film base plate and a manufacturing method thereof. The color film base plate comprises a first black matrix, color resin, a protecting layer and a common electrode which are formed on a base plate, wherein a second black matrix for preventing the reflecting light of the first black matrix from projecting into an array base plate TFT (Thin Film Transistor) channel region is formed on the protecting layer. The manufacturing method of the color film base plate comprises the following steps of: forming a pattern comprising the first black matrix and the color resin on the base plate; forming a pattern comprising the protecting layer and the second black matrix; and forming a pattern comprising the common electrode. By mounting two layers of black matrix patterns, the second black matrix can effectively block the reflecting light reflected from the surface of the first black matrix, which enables the reflecting light reflected from the surface of the first black matrix not to project into the TFT channel region, thereby effectively avoiding the generation of leakage current, improving the retention rate and contrast ratio of voltage at maximum, and enhancing the quality of a liquid crystal display.

Description

technical field [0001] The invention relates to a liquid crystal display and a manufacturing method thereof, in particular to a color filter substrate and a manufacturing method thereof. Background technique [0002] A liquid crystal display (LCD for short) includes an array substrate and a color filter substrate in a cell, and a liquid crystal is arranged therebetween. The array substrate includes gate lines, data lines, pixel electrodes and thin film transistors, the gate lines and data lines perpendicular to each other define a pixel area, the thin film transistors and pixel electrodes are formed in the pixel area, and the gate lines are used to provide turn-on signals to the thin film transistors, The data lines are used to provide data signals to the pixel electrodes, and realize gray scale display by controlling the deflection degree of the liquid crystal. Color filter substrate (also known as color filter, Color Filter) includes black matrix, color resin, protective ...
