Abstract
A liquid crystal display device which includes one image signal line which is connected to a plurality of pixels, a scanning line drive part which outputs an ON voltage to the respective pixels in a predetermined order, and a data line drive part which outputs image signal voltages. The data line drive part outputs a gray level signal voltage corresponding to a gray level value of the pixel as an image signal voltage in a first period, and outputs a correction gray level signal voltage different from the gray level signal voltage as an image signal voltage in a second period which precedes the first period. The liquid crystal display device further includes a control part which generates the correction gray level signal voltage based on the gray level value of the pixel and one or plurality of gray level values of pixels which precede the pixel in order.
