Image display device
On a termination side of each scanning line is provided a charging switching element and a discharging switching element in parallel with each other, the charging switching element having a gate electrode which is connected with one end of a scanning auxiliary line, the other end of which is connected to a scanning line of the same stage, the discharging switching element having a gate electrode which is connected with one end of a scanning auxiliary line, the other end of which is connected to a scanning line of the following stage. Further, the charging switching element has a source/drain electrode which is connected to a scanning line and a selected state scanning driving voltage power source, whereas the discharging switching element has a source/drain electrode which is connected to a scanning line and the non-selected state scanning driving voltage power source, thereby allowing an image display device of the present invention to suppress the dull waveform of a driving voltage at both rise and fall, and prevent erroneous writing without reducing effective writing time.
