A driving apparatus for a multi-color light-emitting display panel
including drive lines and scanning lines intersecting with each other, and
capacitive light-emitting elements which have polarities connected to the
scanning lines and the drive lines at the intersections and which are
divided into a plurality of types by a color of light emission, the
capacitive light-emitting elements of the same type being arranged on each
drive line. The drive apparatus comprises a scanning circuit for
selectively supplying a first potential and a second potential higher than
the first potential to each of the scanning lines, and a drive circuit for
selectively supplying a drive current from a current source and a third a
potential for an offset voltage not higher than a light emission threshold
voltage of the element to each of the drive lines, the drive current and
the third potential are variable.
