Abstract
Each of a plurality of driving circuits constituting a constant current driving apparatus is composed of a first current mirror circuit and a second current mirror circuit. The first current mirror circuit outputs a plurality of output currents, each of which corresponds to a reference current. Accordingly, the variation in the output current can be reduced between the driving circuits adjacent to each other.
