FIG. 2 is a bottom view of the display substrate in FIG. 1. Referring to FIG. 2, the side part 20b of the encapsulating layer 20 in some embodiments substantially surrounds an entire perimeter p of the side surface S3 of the base substrate 10. As shown in FIG. 1 and FIG. 2, a projection of the encapsulating layer 20 on a plane containing the bottom surface S2 of the base substrate 10 substantially covers a projection of the base substrate 10 on the plane containing the bottom surface S2 of the base substrate 10. Optionally, a projection of an outer edge of the encapsulating layer 20 on the plane containing the bottom surface S2 of the base substrate 10 is spaced apart from a projection of an outer edge of the base substrate 10 on the plane containing the bottom surface S2 of the base substrate 10 by a distance d. Optionally, the distance is in a range of 0 μm to approximately 1000 μm, e.g., approximately 1 μm to approximately 1000 μm, approximately 1 μm to approximately 500 μm, approximately 500 μm to approximately 1000 μm, approximately 1 μm to approximately 250 μm, and approximately 1 μm to approximately 100 μm.
