Claim 18:
19. The target substrate according to claim 18, wherein
the first alignment opening comprises a first pillar-shaped through hole and a first flared through hole which are stacked in a direction going away from the base substrate, wherein axes of the first pillar-shaped through hole and the first flared through hole are collinear, and a smaller opening in two openings of the first flared through hole is a first opening, wherein the first opening of the first flared through hole is communicated with an opening of the first pillar-shaped through hole, an orthographic projection of the first opening of the first flared through hole on the base substrate falls within an orthographic projection of the first pillar-shaped through hole on the base substrate, and a portion of the alignment layer in the first pillar-shaped through hole defines the first substrate engaging portion; and
the second alignment opening comprises a second pillar-shaped through hole and a second flared through hole which are stacked in the direction going away from the base substrate, wherein axes of the second pillar-shaped through hole and the second flared through hole are collinear, and a smaller opening in two openings of the second flared through hole is a first opening, wherein the first opening of the second flared through hole is communicated with one opening of the second pillar-shaped through hole, an orthographic projection of the first opening of the second flared through hole on the base substrate falls within an orthographic projection of the second pillar-shaped through hole on the base substrate, and a portion of the alignment layer in the second pillar-shaped through hole defines the second substrate engaging portion.
