Abstract

A liquid crystal display device includes an array substrate having a plurality of pixel electrodes in a matrix form, a counter substrate having a counter electrode opposed to the pixel electrodes, a liquid crystal layer including liquid crystal molecules disposed between the array and counter substrate, a first and second alignment layers, the first alignment layer disposed between the array substrate and the liquid crystal layer, the second alignment layer disposed between the counter substrate and the liquid crystal layer, and each of which are treated so as to give a predetermined pre-tilt angle to the liquid crystal molecules, and a shield electrode disposed a region applied a lateral electric field which is against to a direction of the pre-tilt angle. A potential difference between the shield electrode and the counter electrode is adjusted to a first potential difference during a first period, and the potential difference between the shield electrode and the counter electrode is adjusted to a second potential difference, which is smaller than the first potential difference, during a second period continuing after the first period so as to apply an alternating current voltage between the counter electrode and the shield electrode.
