The driving appartatus can be miniaturized and easily driven. According to the invention, a capacitor, such as a chip capcitor or the like, with a low withstanding voltage can be used in a first-stage amplifier to amplify the video signal from the target electrode. This first-stage amplifier can be arranged near a signal output electrode of the target. Thus, the stray capacitance can be reduced.
