Display substrate and method of manufacturing the same, and display device

Abstract

Embodiments of the present invention disclose a display substrate and a method of manufacturing the same, and a display device comprising the display substrate. The display substrate comprises: a substrate; a black matrix layer and a color filter layer located on the substrate; and at least one main spacer and at least one secondary spacer located on the black matrix layer or the color filter layer and both having direct projections on the substrate within a region where the black matrix layer is located. A sum of thicknesses of portions of the black matrix layer and the color filter layer corresponding to each secondary spacer is smaller than that of portions of the black matrix layer and the color filter layer corresponding to each main spacer, so that a distance from a top end of the secondary spacer to the substrate is smaller than a distance from a top end of the main spacer to the substrate. As a result, a difference between the distance from the top end of the main spacer to the substrate and the distance from the top end of the secondary spacer to the substrate can be varied by adjusting a difference between the sum of thicknesses of the black matrix layer and the color filter layer directly below each main spacer and the sum of thicknesses of the black matrix layer and the color filter layer directly below each secondary spacer, thereby enabling the main spacer and the secondary spacer to provide a good effect of buffering an external force.
