Abstract: A light emitting device according to the present invention includes a flexible wiring board that electrically connects light emitting modules to each other. The light emitting modules include anode-side and cathode-side terminals that are arranged on their back surface and are connected to light emitting elements, which are included in their light emitting module and connected to each other in series or in parallel, in order to supply currents to light emitting elements. The wiring board has a comb shape that includes a number of comb-tooth portions extending in row or column direction of the matrix arrangement of the light emitting modules. The comb-tooth portions include an electrically-conductive pattern. The anode-side and cathode-side terminals of light emitting modules are connected to the electrically-conductive pattern of the comb-tooth portions of the wiring board.
