    A display device of the invention includes horizontal lines, longitudinal lines, electron emission elements, and a scanning circuit which performs the selection of the horizontal lines. The scanning circuit includes a non-selection voltage switch, a correction selection voltage switch, and an output voltage detection switch for the selected horizontal line for every horizontal line. The display device also includes a differential amplifier which is connected to a correction selection voltage input line, a horizontal line selection voltage line, and a correction selection voltage output line for every plurality of horizontal lines. The invention can suppress a voltage drop of the horizontal lines and, at the same time, can suppress the brightness irregularities of the display device.
