Abstract: To provide an information processing system allowing eye-friendly display. The information processing system includes a liquid crystal display device (LCD) as a display unit. An image can be displayed in the LCD by at least two driving methods: a first driving method in which data is sequentially rewritten every frame; and a second driving method in which rewriting of data is stopped after data is rewritten once or more times at the same refresh rate as the first driving method. After the display by the second driving method, each pixel is inversely driven plural times by a signal with an amplitude greater than or equal to 80% and less than or equal to 100% of the maximum amplitude of the data signal, whereby degradation of a liquid crystal material is repaired.

Abstract: To provide a display device with excellent display quality, in a display device including a signal line, a scan line, a transistor, a pixel electrode, and a common electrode in a pixel, the common electrode is included in which an extending direction of a region overlapping with the signal line differs from an extending direction of a region overlapping with the pixel electrode in a planar shape and the extending directions intersect with each other between the signal line and the pixel electrode. Thus, a change in transmittance of the pixel can be suppressed; accordingly, flickers can be reduced.
