1. An array substrate, comprising:
a base substrate;
a pixel definition layer on the base substrate, the pixel definition layer defining subpixel apertures; and
a spacer layer on a side of the pixel definition layer away from the base substrate, wherein the spacer layer comprises first spacers arranged in a first array and second spacers arranged in a second array;
wherein centers of subpixel apertures of two subpixels directly adjacent to an individual first spacer of the first spacers are arranged along a first spacer direction;
centers of subpixel apertures of two subpixels directly adjacent to an individual second spacer of the second spacers are arranged along a second spacer direction;
the first spacer direction is different from the second spacer direction;
a plurality of subpixels are arranged in an array of a plurality of rows along a first direction and a plurality of columns along a second direction;
a respective row of first spacers is along the first direction;
a respective row of second spacers is along the first direction;
adjacent first spacers in the respective row of first spacers along the first direction are spaced apart from each other by a first row distance;
adjacent second spacers in the respective row of second spacers along the first direction are spaced apart from each other by a second row distance; and
a ratio of the first row distance to the second row distance is in a range of 0.8 to 1.2;
wherein a second subpixel aperture, a third subpixel aperture, a fourth subpixel aperture respectively extending through the pixel definition layer, wherein a second light emitting layer, a third light emitting layer, and a fourth light emitting layer respectively connected to a second anode, a third anode, and a fourth anode, respectively through the second subpixel aperture, the third subpixel aperture, the fourth subpixel aperture;
a respective one of the first spacers is between the second subpixel aperture and the third subpixel aperture; and
a respective one of the second spacers is between the third subpixel aperture and the fourth subpixel aperture.
