ABSTRACT:
An organic EL element drive circuit including a reference current setting circuit for at least one of three primary display colors, the reference current setting circuit comprises a first reference current generator circuit for generating a reference current, a second reference current generator circuit responsive to a first setting data for generating a current as a reference for luminance regulation on a basis of the reference current generated by the first reference current generator circuit and a reference current correction circuit for generating a corrected reference current as said predetermined reference current by adding a current according to a second setting data to a reference current generated by said second reference current generator circuit or subtracting a current according to said second setting data from said reference current generated by said second reference current generator circuit. The first and second setting data are set from the outside of the organic EL element drive circuit.
