Display device and driving method |
| abstract |
An object is to reduce power consumption of a display device and to suppress deterioration of display quality. As a transistor provided for each pixel, a transistor including an oxide semiconductor layer is used. Note that off-state current of the transistor can be decreased when the oxide semiconductor layer is highly purified. Therefore, variation in the value of a data signal due to the off-state current of the transistor can be suppressed. That is, display deterioration (change) which occurs when writing frequency of the data signal to the pixel including the transistor is reduced (when a break period is lengthened) can be suppressed. In addition, flickers in display which generates when the frequency of an alternating-current driving signal supplied to a signal line in the break period is reduced can be suppressed. |
