Such a semiconductor integrated circuit for driving light-emitting elements constitutes at least part of a light-emitting element driving device configured to vary the number of lamps in which a plurality of light-emitting elements are connected in series. The semiconductor integrated circuit for driving the light emitting elements has a variable resistance control unit configured to increase a resistance value of a variable resistor connected in series with the plurality of light emitting elements immediately before and at the same time when the number of lamps decreases.
