In drive circuit for organic EL elements performing multicolor light
emission, DC power supply circuits 21,22 and 23 are provided for each
emitted color of light, so as to supply a voltage that differs, depending
upon the color of light emitted, thereby reducing the amount of power loss
that occurred in the current drive circuit 31,32 and 33 because of the
differences in the voltage versus intensity characteristics of each
emitted color EL elements.
