The present disclosure provides a high-precision dimming circuit.A dimming circuit (107) includes an input stage (IN) and an output stage (OUT). The input stage (IN) includes a plurality of amplifiers (AMP1 to AMP3) which have non-inverted input terminals (+) thereof inputted with different dimming input voltages (DCDIM1, DCDIM2 and VH), respectively, and inverted input terminals (−) thereof inputted with a common dimming output voltage (V3). The output stage (OUT) is connected between respective output terminals of the plurality of amplifiers (AMP 1 to AMP3) and an output node of the diming output voltage (V3), and outputs, among the plurality of dimming input voltages (DCDIM1, DCDIM2 and VH) respectively inputted to the plurality of amplifiers (AMP1 to AMP3), a lowest voltage as the dimming output voltage (V3).
