Abstract: A mother board for a display panel, having a bonding region and a first panel region including a retaining region and a peripheral region, in which: a first light-emitting functional layer is located in the first panel region; a first adhesive layer surrounding the first panel region is adhered to a cover plate and a base substrate, and an orthographic projection of an edge of the first adhesive layer close to the bonding region on the base substrate defines a first pattern; the first light-emitting functional layer in the retaining region and the peripheral region are spaced by a first spacing layer, an orthographic projection of which on the base substrate partially overlaps with the first pattern and form a closed second pattern therewith. The orthographic projection of the first spacing layer on the base substrate is located within that of the first adhesive layer on the base substrate.
