WIPO Patent Application WO/2019/216268
Kind Code:
A1
Abstract:
This display device 1 has transparent circuit boards 2A, 2B, and a plurality of light emitting elements L arranged in a matrix pattern on the circuit boards 2A, 2B. The light emitting elements L each comprise a pair of terminals TA, TB to which a driving voltage is applied in order to emit light. The circuit boards 2A, 2B comprise a plurality of row wires 3 connecting in common one of the terminals TA belonging to the plurality of light emitting elements L positioned on the same row in the matrix pattern arrangement, and a plurality of column wires 4 connecting in common the other terminals TB belonging to the plurality of light emitting elements L positioned on the same column in the matrix pattern arrangement. At each intersection X of the plurality of row wires 3 and the plurality of column wires 4, the row wires 3 and the column wires 4 are formed on different surfaces of the circuit boards 2A, 2B.
