  • Patent number: 12342711
    Abstract: A display substrate and a mask plate assembly includes a base substrate, a pixel defining layer, a functional layer, a cathode layer, and a covering layer that are sequentially stacked in a direction away from the base substrate, wherein the size of orthographic projection of the functional layer on the base substrate is jointly determined by the size of a display area and a first minimum distance. The first minimum distance is the minimum distance in a direction from the display area to a non-display area and between the boundary of the display area and the boundary of the functional layer, and is determined by a first shadow width of the functional layer extending from the display area to the non-display area. The first shadow width is the maximum width of a shadow area formed within a preset region when the functional layer is vapor deposited in the preset region.
