An object is to reduce parasitic capacitance of a signal line included in a liquid crystal display device. A transistor including an oxide semiconductor layer is used as a transistor provided in each pixel. Note that the oxide semiconductor layer is an oxide semiconductor layer which is highly purified by thoroughly removing impurities (hydrogen, water, or the like) which become electron suppliers (donors). Thus, the amount of leakage current (off-state current) can be reduced when the transistor is off. Therefore, a voltage applied to a liquid crystal element can be held without providing a capacitor in each pixel. In addition, a capacitor wiring extending to a pixel portion of the liquid crystal display device can be eliminated. Therefore, parasitic capacitance in a region where the signal line and the capacitor wiring intersect with each other can be eliminated.

A display device and a display driving method are provided. The display device includes a display panel and a timing controller. A timing controller is configured to drive the display panel. A memory is configured to store previous image data. The timing controller sequentially receives a plurality of current image data during an image update period, and compares the plurality of current image data to the previous image data to sequentially generate a plurality of driving signals. The timing controller sequentially outputs the plurality of driving signals to the display panel during the screen update period to update a display screen of the display panel.
