1. A spliced display device, wherein the spliced display device comprises:
at least two spliced liquid crystal display panels, wherein each of the liquid crystal display panels comprises a main body portion, wherein the main body portion comprises an array substrate, an opposite substrate, and a sealant; the array substrate and the opposite substrate are spaced from each other and bonded by the sealant; and the array substrate extends toward a side of the main body portion close to an adjacent liquid crystal display panel to form an extension portion; wherein main body portions and extension portions of adjacent liquid crystal display panels are collectively enclosed to form a groove, and an opening of the groove faces a light-exiting side of the liquid crystal display panels; and
a light-emitting diode (LED) light-emitting unit disposed in the groove;
wherein the spliced display device further comprises a transparent package filled in the groove and covering the LED light-emitting unit;
wherein the opposite substrate further includes a polarizer provided on the side of the substrate away from the array substrate, and the transparent package includes the first transparent encapsulation layer and the second transparent encapsulation layer disposed on a side of the first transparent encapsulation layer away from the LED light-emitting unit;
wherein a height of the first transparent encapsulation layer is equal to a height of the substrate, and a height of the second transparent encapsulation layer is equal to a height of the polarizer.
