ABSTRACT:
To provide a circuit for preventing degradation of a display quality caused by horizontal crosstalk. An image signal correcting circuit supplies a corrected image signal to a display panel to apply the image signal using the corresponding data line after pre-charging each data line to the predetermined voltage, for a pixel electrode located at the selected scanning line. The image signal correcting circuit comprises a subtractor312for calculating a difference between a gray scale level shown as a reference signal Ref and a gray scale level of the pixel indicated by an image signal VID, an integrator314for integrating the result of the subtraction output to one row of pixel located at the selected scanning line, and an adder322that provides the integration Int multiplied by the coefficient k1as the corrected image signal.
