Abstract: A liquid crystal display device includes: pixel electrodes to each of which a potential corresponding to a gray-scale value is applied, for a plurality of pixels arranged in a matrix in a display area, via a pixel transistor of each of the pixels; a common electrode forming, in cooperation with the pixel electrode, an electric field to align a liquid crystal composition; a plurality of scanning signal lines each connected in common to gates of the pixel transistors of the plurality of pixels constituting each of a plurality of rows forming the matrix; and a driver circuit setting, after powering on and before displaying an image in the display area, the common electrode into a high impedance state and then setting the scanning signal line to an inactive potential to cut off a source and a drain of the pixel transistor from each other.
