ABSTRACT:
A display apparatus has a display panel, which is provided with a plurality of scanning electrodes and a plurality of signal electrodes arranged in a matrix shape, and a plurality of EL elements connected to the scanning electrodes and the signal electrodes at intersections thereof. A driving circuit for the display apparatus is provided with: a driving device for supplying a constant current driving signal to the signal electrodes in correspondence with an input signal, to drive the display panel; a detection device for detecting a voltage drop in a forward direction of the EL element, and outputting a detection signal which indicates the detected voltage drop; and a control device for controlling voltage, which is supplied to the driving device, to have a predetermined voltage value in correspondence with the detection signal from the detection device.
