    • 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.
    • 一种液晶显示装置,具有:具有矩阵状的多个像素电极的阵列基板,具有与像素电极相对的对置电极的对置基板,配置在该阵列与对置基板之间的液晶分子的液晶层, 第一和第二取向层,设置在阵列基板和液晶层之间的第一取向层,设置在对置基板和液晶层之间的第二取向层,并且每个对准层被处理, 倾斜角与液晶分子的倾斜角度,以及屏蔽电极,该屏蔽电极设置了施加横向电场的区域,该横向电场抵抗预倾角的方向。 屏蔽电极和对置电极之间的电位差在第一期间被调整到第一电位差,并且屏蔽电极和对电极之间的电位差被调整到小于第一电位的第二电位差 在第一时段之后的第二时段期间,在对电极和屏蔽电极之间施加交流电压。
