A driving apparatus of a display panel performs a high speed operation with a construction having a small scale. The driving apparatus is constituted by a DC power source to generate a DC voltage, a first capacitor connected in parallel with the DC power source, a coil whose one end is connected to a positive side terminal of the DC power source, switching device which alternately connects and disconnects the other end of the coil to a negative side terminal of the DC power source, a diode whose anode is connected to the other end of the coil and whose cathode is connected to the negative side terminal of the DC power source, and a second capacitor connected in parallel with the diode. A change in electric potential occurring at the other end of the coil is outputted as a driving pulse.
