1. A micro light-emitting diode carrier board, comprising:
a substrate structure having a first surface and a second surface and having a central region and a peripheral region located outside the central region;
a plurality of micro light-emitting diode elements forming an array and located on the second surface of the substrate structure; and
a patterned structure formed on the first surface or the second surface, wherein the plurality of micro light-emitting diode elements is overlapped and disposed on the patterned structure, the patterned structure has a first pattern density in the central region and has a second pattern density in the peripheral region, and the first pattern density is different from the second pattern density.
