COLOR FILTER SUBSTRATE, MANUFACTURING METHOD THEREOF AND DISPLAY DEVICE

摘要

A color filter substrate, a manufacturing method thereof and a display device are provided. The color filter substrate includes: a transparent base (1); a color filter layer (2) disposed on the transparent base (1) and at least including a plurality of color filter units; a protective layer (3) disposed on the color filter layer (2); a plurality of auxiliary electrodes (4) disposed on the protective layer (3), with a position of each of the auxiliary electrodes (4) corresponding to a connecting position between two adjacent the color filter units; a black matrix (5) disposed on the auxiliary electrode (4) and partially covering the auxiliary electrode (7); a spacer (6) disposed on the black matrix (5); and a transparent electrode (7) disposed on the spacer (6) and electrically connected with the auxiliary electrode (4) in an area of the auxiliary electrode (4), not covered by the black matrix (5). The color filter substrate, by providing the black matrix on the auxiliary electrodes, can effectively reduce the lateral light leakage caused by the light reflection of the auxiliary electrodes, improve the aperture opening ratio, reduce the thickness of the spacer, and increase the yield. Meanwhile, the function of reducing the number of mask plates can be achieved to reduce the cost.
