Manufacturing method of splicing display panel and splicing display panel

A manufacturing method of a splicing display panel, comprising:

• step B1:
• providing at least two backplates, wherein light-emitting devices are disposed on surfaces of the at least two backplates;
• step B2:
• forming first encapsulation layers on the at least two backplates, wherein the first encapsulation layers cover the light-emitting devices;
• step B3:
• disposing the at two backplates on a transparent substrate, wherein the first encapsulation layers are disposed between the at least two backplates and the transparent substrate, and lateral surfaces of two adjacent backplates and the transparent substrate enclose to form grooves;
• step B4:
• forming second encapsulation layers in the grooves to obtain an encapsulation semi-finished product;
• and
• step B5:
• forming a third encapsulation layer on peripheral sides of the encapsulation semi-finished product.
