The invention intends to realize long lifetime of electron-emitter elements and a display apparatus by preferably eliminating charges accumulated in the electron-emitter elements. The display apparatus of the invention has: a non-display period extending circuit for extending a non-display period of an input video signal to a period longer than the non-display period of the input video image and outputting the extended signal; a plurality of electron-emitter elements for emitting electrons on the basis of the video signal outputted from the non-display period extending circuit; and a scan driver having a pulse applying circuit for applying a pulse signal to the electron-emitter elements in the non-display period of the video signal extended by the non-display period extending circuit. A pulse width of the pulse signal is set to be longer in accordance with the extended non-display period.
