Abstract
A color filter substrate, a preparing method thereof and a display device are provided. The method includes: preparing a black matrix pattern and a color filter pattern on a substrate; preparing planarization layer and spacers including primary spacers and secondary spacers. The black matrix pattern includes primary areas and secondary areas, and the primary area has a width in the column direction of the black matrix pattern greater than the width of the secondary area in the column direction of the black matrix pattern. The primary spacers are located on primary areas of the black matrix pattern; and the secondary spacers are located on secondary areas of the black matrix pattern, the primary spacers have a height greater than that of the secondary spacers.
