Display substrate, fine metal mask set and manufacturing method thereof

A display substrate, comprising:

• a base substrate;
• and
• a plurality of repeat units on the base substrate, wherein each of the plurality of repeat units comprises one first-color sub-pixel, one second-color sub-pixel pair and one third-color sub-pixel which are arranged in a first direction, the second-color sub-pixel pair comprises two second-color sub-pixels arranging in a second direction, the plurality of repeat units are arranged in the first direction to form a plurality of repeat unit groups, the plurality of repeat unit groups are arranged in the second direction, and adjacent repeat unit groups in the plurality of repeat unit groups are staggered from each other in the first direction,
• wherein each sub-pixel comprises a light-emitting layer, and light-emitting layers of adjacent sub-pixels of two different colors in the first direction are connected with each other;
• light-emitting layers of the third-color sub-pixel and the second-color sub-pixel which are adjacent to each other in the second direction are connected with each other;
• and
• a spacing is disposed between the light-emitting layer of the first-color sub-pixel and the light-emitting layer of at least one of the second-color sub-pixel and the third-color sub-pixel which are adjacent to the first-color sub-pixel in the second direction.
