LIQUID CRYSTAL DISPLAY DEVICE AND ELECTRONIC DEVICE INCLUDING THE LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
In a liquid crystal display device including a plurality of pixels in a display portion and configured to performed display in a plurality of frame periods, each of the frame periods includes a writing period and a holding period, and after an image signal is input to each of the plurality of pixels in the writing period, a transistor included in each of the plurality of pixels is turned off and the image signal is held for at least 30 seconds in the holding period. The pixel includes a semiconductor layer including an oxide semiconductor layer, and the oxide semiconductor layer has a carrier concentration of less than 1×1014/cm3. |
