Abstract
A first sample-and-hold circuit samples and holds an input image signal so as to output an image signal to be applied to a data line causing noise. A correction circuit produces a correcting signal according to the image signal and a pre-charging voltage. An addition circuit adds up an image signal to be applied to a data line affected by the noise and the correcting signal so as to produce a corrected image signal. Consequently, when scanning lines are selected sequentially for each of blocks, into which a plurality of data lines is grouped, in order to display an image, irregular luminance occurring in portions of the displayed image coincident with the borders of the blocks is suppressed to be indiscernible.
