Patent ID: 6873313

Claim:
An image display device, comprising: a plurality of pixels disposed in a matrix; a display section, having a plurality of data signal lines for respective columns of the plurality of pixels and having a plurality of scanning signal lines corresponding to respective rows of the plurality of pixels, for displaying an image by writing a video signal from each data signal line into each pixel in synchronism with a scanning signal which is outputted from each scanning signal line; a data signal line driving circuit for outputting the video signal to the plurality of data signal lines; a scanning signal line driving circuit for outputting the scanning signal to the plurality of scanning signal lines; a pre-charging circuit for writing a pre-charging voltage inputted in synchronism with a pre-charging control signal into the plurality of data signal lines in a predetermined period of time; and wherein a pre-charging voltage stabilizing section for stabilizing a pre-charging voltage and supplying the stabilized pre-charging voltage as said pre-charging voltage to the pre-charging circuit, so as to suppress fluctuation in said pre-charging voltage is provided on a preceding stage of said pre-charging circuit; and wherein said pre-charging voltage stabilizing section includes current controlling means composed of a resistor and charge holding means composed of a capacitance, where charge is supplied from the charge holding means when the pre-charging control signal is working and pre-charge voltage supplied from the control signal generating circuit is applied to the charge holding means while the precharging control signal is not working, and current controlling means is used.
