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.
