At least a portion of the lattice area 320 may be obscured by the first area 312 .

The auxiliary lattice area 321 may have a width smaller than the width of the lattice area 320 in the short side direction (x-axis direction), but is not limited thereto. For example, the number of openings formed in the auxiliary lattice area 321 may be less than the number of openings formed in the lattice area 320.

In some embodiments, protrusions 304 may extend from each of the plurality of bars 310 . For example, the protrusions 304 may be formed to extend from one surface 317 of the plurality of bars 310 in the longitudinal direction (y-axis direction). As described above, the protrusions 304 may be formed to protrude in all or part of the first longitudinal direction (+y-axis direction) and/or the second longitudinal direction (-y-axis direction) of the plurality of bars 310.
