Abstract
A display substrate motherboard and a preparation method thereof, a display substrate and a preparation method thereof are disclosed. The display substrate motherboard includes a base substrate, a first flexible organic layer, a first inorganic layer, a second flexible organic layer and a pixel driving circuit layer. The pixel driving circuit layer includes a plurality of pixel driving circuit portions respectively used for a plurality of display substrates, and the plurality of pixel driving circuit portions are insulated from each other. An orthogonal projection of the second flexible organic layer on the base substrate is located inside an orthogonal projection of the first inorganic layer on the base substrate. An orthogonal projection of each of the pixel driving circuit portions on the base substrate is located inside the orthogonal projection of the second flexible organic layer on the base substrate.
