1. A display device, comprising:
a transparent circuit board; and
a plurality of light-emitting elements arrayed in a matrix on the transparent circuit board,
the plurality of light-emitting elements each including a pair of terminals to which drive voltage for light emission is applied,
the transparent circuit board including
a plurality of row wires each connecting ones of the pairs of terminals of ones of the plurality of light-emitting elements to each other, the ones of the plurality of light-emitting elements belonging to a same one of rows in the matrix array, and
a plurality of column wires each connecting other ones of the pairs of terminals of ones of the plurality of light-emitting elements to each other, the ones of the plurality of light-emitting elements belonging to a same one of columns in the matrix array,
the plurality of row wires and the plurality of column wires being formed on different surfaces of the transparent circuit board at intersection portions of the plurality of row wires and the plurality of column wires,
the plurality of column wires being formed on a front surface of the transparent circuit board at the intersection portions of the plurality of row wires and the plurality of column wires,
the plurality of row wires being formed on a rear surface of the transparent circuit board at the intersection portions of the plurality of row wires and the plurality of column wires,
the plurality of row wires including one or more pairs of row wires, the one or more pairs of row wires including parts
that are located on an outside of a region where the plurality of light-emitting elements are arrayed in a plan view of the transparent circuit board, and
that are formed on the different surfaces of the transparent circuit board such that at least the parts overlap with each other in the plan view of the transparent circuit board,
the one or more pairs of row wires including one row wire that is traversed from the rear surface to the front surface through one of the vias, the one of the vias being connected to one of the pair of terminals of one of the plurality of light-emitting elements, the one of the plurality of light-emitting elements belonging to an outermost one of the columns in the matrix array.
