An LED device comprises first to N-th (N is an integer of 2 or more) LEDs each having one end connected to one another and having different emission colors, and first to N-th transistors each having one end connected to the other ends of the individual LEDs and the other end connected to one another. The first to N-th transistors configure a current mirror circuit. A drive current supplied from outside is distributed to the individual LEDs at a current ratio corresponding to a size ratio of the individual transistors.
