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 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.
