ABSTRACT:
An illuminant substrate includes a substrate, first and second light emitting members provided on the substrate, a first anode covering the first light emitting member, a second anode covering the second light emitting member, a resistor located between the first and second light emitting members and electrically connecting the first and second anodes, and a rib laminated on the resistor. A side face of the resistor facing the first light emitting member projects toward the first light emitting member further than a side face of the rib facing the first light emitting member, and a side face of the resistor facing the second light emitting member projects toward the second light emitting member further than a side face of the rib facing the second light emitting member. In addition, the side faces of the resistor facing the first and second light emitting members are forward tapered faces, the side face of the rib is a reverse tapered face, and the first anode and the second anode are physically divided by the rib.
