ABSTRACT:
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.
