<p>Provided is an LED driving device which can stably reduce brightness of an LED. The LED driving device provided with: a driving voltage switching means (Q1008) for switching between a first driving voltage and a second driving voltage in accordance with a timing signal; and feedback circuits (Q1001 to Q1005) to which any one of the first and second driving voltages is applied and which thereby determine a current flowing through an LED. The feedback circuits are provided with a resistor switching means (Q2001) for switching, in accordance with the timing signal, between resistors (R1001, R1002, and R2001) that determine the current flowing through the LED.</p> |
