Abstract: A novel liquid crystal display device without a decrease in display quality. The liquid crystal display device includes a pixel for displaying a still image at a frame frequency of less than or equal to 1 Hz, and a liquid crystal layer in the pixel has a dielectric constant anisotropy of greater than or equal to 2 and less than or equal to 5. With the above structure, a change in voltage applied to a pixel can be kept within an acceptable range of a deviation in gray level for displaying the same still image. Thus, flickers due to a low refresh rate can be reduced, which leads to an increase in display quality.

Abstract: A flicker of an FFS liquid crystal display device that is driven at a low refresh rate is reduced. In an FFS liquid crystal display, a pixel electrode and a first common electrode included in a liquid crystal element are formed on an element substrate side, and a second common electrode is formed on another substrate (counter substrate) side. By making the first and second common electrodes have the same potential, generation of a residual DC voltage can be suppressed in a pixel. Thus, even when a refresh rate is lowered, change in transmittance of a pixel can be suppressed in a data retention period, so that a flicker can be reduced.

Abstract translation: 以低刷新率驱动的FFS液晶显示装置的闪烁减少。 在FFS液晶显示装置中，在元件基板侧形成像素电极和包含在液晶元件中的第一公共电极，在另一基板（对置基板）侧形成第二公共电极。 通过使第一和第二公共电极具有相同的电位，可以在像素中抑制残留DC电压的产生。 因此，即使当刷新率降低时，也可以在数据保持期间抑制像素的透射率的变化，从而能够降低闪烁。
