1. A worktable for laser processing comprising:
a lower plate including:
a first area;
a second area surrounding the first area;
a third area surrounding the second area;
support parts protruding from the lower plate in the first area and the third area;
internal blocks disposed on the lower plate in the first area; and
external blocks disposed on the lower plate in the third area and surrounding the internal blocks, wherein
a side surface of each of the internal blocks and a side surface of each of the external blocks are inclined such that an area of an upper surface of each of the internal blocks is larger than an area of a lower surface of each of the internal blocks, and an area of an upper surface of each of the external blocks is larger than an area of a lower surface of each of the external blocks,
the second area has a polygonal shape and includes a first side parallel to a first direction, a second side parallel to a second direction intersecting the first direction, and a third side parallel to a third direction intersecting the first direction and the second direction, and
the internal blocks include:
at least one first internal block having a first shape including a side parallel to the third direction; and
second internal blocks having a second shape different from the first shape and not including a side parallel to the third direction.
