An organic EL display device having an organic EL drive circuit has a
reference current generation circuit that switches the column line drive
in response to changing of the dot arrangement of R, G and B through
changeover switch circuits. Three D/A converter blocks constituted by a
plurality of switch circuits and a plurality of output side transistors
of a current mirror circuit are provided to produce reference currents
for R, G and B that are selectively switched by a first, a second and a
third changeover switch circuit. As a result, the D/A converter blocks
corresponding to the respective terminal pins dynamically produce drive
currents for the respective terminal pins so as to correspond to the dot
arrangement of R, G and B on the organic EL panel.
