Abstract
A display apparatus and a driving circuit of a display panel, in which even when an anode line driving circuit is made of a plurality of IC chips, light emission luminance values on the display panel can be uniformed. The display apparatus is made of a plurality of driving circuits having a plurality of light-emission drive current sources each for generating a light-emission drive current to allow a light emitting element of the display panel to emit the light and supplying the light-emission drive current to first electrode lines of the display panel. At least one of the driving circuits is provided with a drive current control circuit for adjusting a current amount of the light-emission drive current to be generated by the driving circuit on the basis of the light-emission drive current generated from the other driving circuit.
