Patent ID: 7535439

Claim:
A display device comprising: a display panel including a plurality of scanning wiring lines, a plurality of data wiring lines intersecting with the scanning wiring lines, a plurality of electron emission elements connected to both of the wiring lines, and phosphors which emits light by electrons from the electron emission elements; scanning wiring line drivers connected to the scanning wiring lines; data wiring line drivers connected to the data wiring lines; and an irradiation circuit for converging the electrons from the electron emission elements to irradiate the phosphors with the electrons, a scanning wiring line driver comprising: a detection circuit including a selection switch which brings the scanning wiring line into a selected state, a non-selection switch which brings the scanning wiring line into a non-selected state, and a feedback switch which detects a potential of each scanning wiring line; and a correction circuit which corrects the scanning wiring line potential into a predetermined potential every scanning wiring line based on the scanning wiring line potential detected by the feedback switch, the detection circuit including a capacitance of the feedback switch and a wiring line capacitance, wherein a time constant formed of an on-resistance value of the feedback switch, the capacitance of the feedback switch, and the wiring line capacitance is smaller than a time constant formed of an on-resistance value of the selection switch and a capacitance of the display panel.
