摘要： The present disclosure provides a color filter substrate and a manufacturing method thereof, and a display device. The color filter substrate comprises a plurality of pixel regions and a matrix provided between every two adjacent pixel regions, the pixel region comprises a color filter layer and the color filter layer and the matrix are partially overlapped. Wherein, a height compensation part is provided above the color filter layer, and a top surface of the height compensation part is configured to be planar so as to compensate for unevenness of a surface of the color filter layer.
