要約
(EN)
Provided is an image pick-up device capable of appropriately deflecting an electron beam while suppressing the reduction of an aperture ratio. The image pick-up device (1) comprises: a plurality of electron emission sources (23) arranged in a matrix in a horizontal scanning direction and in a vertical scanning direction, each constituting a pixel, and emitting electron beams; a first deflection electrode (52) and a second deflection electrode (53) having a plurality of first strip-shaped electrodes (54) and a plurality of second strip-shaped electrodes (56) disposed alternately in the vertical scanning direction on mutually opposite sides of each pixel line in the horizontal scanning direction and deflecting the electron beams in the vertical scanning direction on a per each pixel line basis; and a vertical deflection power supply unit (58) for variably applying a deflection voltage to each of the first deflection electrode (52) and the second deflection electrode (53) so that a forward/reverse voltage difference occurs at least between the first deflection electrode (52) and the second deflection electrode (53).
