Display substrate and display apparatus with enhanced light transmittance

A display substrate, comprising a first display area and a second display area, wherein the display substrate comprises:

• a base substrate;
• a plurality of first repeating units, arranged on the base substrate in an array along a first direction and a second direction, and located in the first display area, each of the first repeating units comprising a plurality of sub-pixels that comprise:
• a first sub-pixel and a second sub-pixel that are alternately arranged in each of the first direction and the second direction, and a plurality of third sub-pixels arranged in an array along the first direction and the second direction;
• and
• a plurality of second repeating units, arranged on the base substrate in an array along the first direction and the second direction, and located in the second display area, each of the second repeating units comprising a plurality of sub-pixels,
• wherein the first repeating unit has a first pitch equal to a distance, along the first direction, between centers of two first sub-pixels that are respectively located in two adjacent first repeating units and are located in a same row;
• the second repeating unit has a second pitch equal to a distance, along the first direction, between centers of two first sub-pixels that are respectively located in two adjacent second repeating units and are located in a same row, the first pitch being greater than the second pitch;
• and
• within one of the first repeating units, a distance between centers of two adjacent sub-pixels along the first direction is a first distance, and the first distance and the second pitch are in a following relationship:
• 0.3×the second pitch≤the first distance≤0.8×the second pitch;
• and
• wherein in two adjacent first repeating units along the first direction, a distance, along the first direction, between centers of two sub-pixels that are respectively located in the two first repeating units and are adjacent to each other along the first direction is a first spacing;
• and
• a number of the plurality of sub-pixels within the first repeating unit is larger than a number of the plurality of sub-pixels within the second repeating unit, and the first spacing is greater than the first distance.
