Abstract

Disclosed is a liquid crystal display device and a driving method thereof for displaying an image, in which the polarity of a voltage applied to the liquid crystal element is inverted in a first frame period and a second frame period which are sequential. The voltage applied to the liquid crystal element is compensated in the case where images of the first frame period and the second frame period are judged as a still image as a result of comparison of the image of the first frame period with the image of the second frame period and the absolute value of the voltage applied to the liquid crystal element in the first frame period is different from that of the voltage applied to the liquid crystal element in the second frame period.

First claim

What is claimed is:

1. A method for driving a liquid crystal display device, the liquid crystal display device comprising:
a pixel portion comprising a plurality of pixels, one of the plurality of pixels comprising:
a liquid crystal element comprising a first terminal and a second terminal;
a capacitor comprising a first terminal and a second terminal;
a transistor comprising:
a gate electrically connected to a scan line;
a first terminal electrically connected to a signal…
