Abstract
A liquid crystal display device that performs intermittent driving involving a driving period and an idle period includes a gray scale level control unit that generates, from an input image signal, an image signal for display and an image signal for correction. A signal line control unit writes the image signal for correction to the plurality of signal lines before writing the image signal for display during a driving period. An LUT stores a correction gray scale value associated with a gray scale value of at least a current frame. An adding circuit corrects the input image signal based on the correction gray scale value read from the LUT. The subtracting circuit specifies, in a pixel region, a regular image pattern including at least a first pixel and a second pixel and changes an output from the adding circuit for the first image by a predetermined gray scale width.
