Provided is an LED driving device which can stably reduce brightness of an LED. The LED driving device is provided with a driving voltage switching means (Q1008) for switching a first driving voltage to/from a second driving voltage, corresponding to a timing signal, and feedback circuits (Q1001-Q1005) which have the first driving voltage or the second driving voltage applied and determine a current that flows in the LED. The feedback circuits are provided with a resistor switching means (Q2001) for switching resistors (R1001, R1002, R2001), which determine the current that flows in the LED corresponding to the timing signal. |
