Abstract
A display substrate and a method of manufacturing the same, and a display device, are disclosed. The display substrate includes a control portion and a color portion, the control portion and the color portion both including position aligning regions at corresponding positions and further including position aligning marks provided in the position aligning regions. The black matrix is located on top of the color portion and at least the position aligning marks in the color filter layer are formed in a hollowed-out structure. The position aligning marks has an increased level drop or height difference, such that more accurate position alignment may be achieved by identifying the position aligning marks based on height difference at edge of standard pattern.
