The method includes providing a base substrate; forming an array layer on a side of the base substrate; forming a light-emitting structure layer on a side of the array layer away from the base substrate, where the light-emitting structure layer includes a plurality of light-emitting units; and forming a light-blocking layer on a side of the light-emitting structure layer away from the base substrate, where the light-blocking layer includes a black matrix and openings. Before forming the openings, the method further includes forming a first inorganic layer between the light-emitting structure layer and the light-blocking layer, where the first inorganic layer at least includes first sub-portions; and a vertical projection of a first sub-portion on the base substrate overlaps a vertical projection of a corresponding opening on the base substrate.
