Optionally, in the light-emitting element encapsulation structure according to some embodiments of this disclosure, as illustrated in FIG. 3 and FIG. 4, the light-emitting element encapsulation structure can include a display area AA (an area including an orthographic projection of the light-emitting element 5 onto the first substrate 01), a first peripheral area S1 located around the display area AA and surrounding the display area AA, and a second peripheral area S2 located around the first peripheral area S1 and surrounding the first peripheral area S1, where a non-display area can optionally include the first peripheral area S1 and the second peripheral area S2, and the encapsulation layer 3 is arranged in the non-display area, and can optionally be only arranged in a part of the non-display area, e.g., in the second peripheral area S2, or can be arranged in both the second peripheral area S2, and a part of the first peripheral area S1.

Optionally, in the light-emitting element encapsulation structure according to some embodiments of this disclosure, as illustrated in FIG. 3 and FIG. 4, the distance d between an orthographic projection of the encapsulation layer 3 onto the first substrate 1, and an orthographic projection of the light-emitting element 5 onto the first substrate 1 is less than or equal to 0.5 mm.
