Display substrate and display device

A display device, comprising a display area;

• wherein the display area comprises:
• a first display sub-area;
• and
• a second display sub-area, provided with a camera, wherein:
• the first display sub-area comprises a plurality of groups of pixels, each group of pixels comprises a first pixel element and a second pixel element, each group of pixels comprises a first sub-pixel, two second sub-pixels and a third sub-pixel;
• the two second sub-pixels are located between the first sub-pixel and the third sub-pixel in a row direction;
• the plurality of groups of pixels are arranged in the row direction to form a plurality of rows of pixels, and the plurality of rows of pixels are arranged along a column direction;
• the second display sub-area comprises a plurality of third pixel elements, each third pixel element comprises a first sub-pixel, a second sub-pixel and a third sub-pixel arranged adjacent to each other, the plurality of third pixel elements are arranged in the row direction to form a plurality of rows of pixel, the plurality of rows of pixels are arranged along the column direction, and lines connecting centers of the first sub-pixel, the second sub-pixel and the third sub-pixel in each third pixel elements form a triangle;
• and,
• a distribution density of pixels in the first display sub-area is greater than a distribution density of pixels in the second display sub-area;
• wherein in the second display sub-area, the plurality of third pixel elements are arranged in a checkerboard pattern;
• the plurality of third pixel elements are arranged in an alternating column configuration in the row direction and in an alternating row configuration in the column direction;
• a distance between two adjacent third pixel elements in a same row is not less than a size of one third pixel element in the row direction;
• and a distance between two adjacent third pixel elements in a same column is not less than a size of one third pixel element in the column direction.
