Claim:
A display comprising: a pixel array including scan lines extending laterally, signal lines extending longitudinally, pixels arranged in a matrix so as to correspond to the intersections of the scan lines and the signal lines, and auxiliary scan lines extending parallel to the scan lines; a vertical scan circuit for sequentially applying selection pulses to the scan lines to sequentially select the pixels row by row; a horizontal drive circuit for supplying a signal, of which potential is reversed between a high level and a low level relative to a predetermined reference potential, to each signal line to write the signal with a high or low potential to the pixels in the selected row; and an auxiliary scan circuit, operatively associated with the vertical scan circuit, for sequentially applying auxiliary pulses to the auxiliary scan lines, wherein each pixel comprises a transistor, which connects to the corresponding scan line and signal line and conducts in response to the selection pulse, a pixel electrode to which the signal is written through a corresponding conducting transistor, and an auxiliary capacitor for holding the written signal, one electrode of each auxiliary capacitor is connected to a corresponding transistor and another electrode thereof is connected to the corresponding auxiliary scan line that is common to the auxiliary capacitors in the same row, and the auxiliary scan circuit sequentially applies the auxiliary pulses, of which potential is reversed between the high level and the low level relative to the predetermined reference potential, to the auxiliary scan lines synchronously with the selection pulses to control such that the potential of the electrode of each auxiliary capacitor in the selected row is opposite in polarity to that of the signal written in the corresponding pixel electrode in the selected row, and further control such that the potential of the electrode of each auxiliary capacitor is returned to the reference potential when the selected row is released.
