摘要： An object is to suppress deterioration of a displayed image even when a refresh rate is reduced in displaying a still image. A liquid crystal display device includes a pixel transistor electrically connected to a pixel electrode, and a capacitor having one electrode electrically connected to the pixel electrode and the other electrode electrically connected to a capacitor line. The pixel transistor is turned on and a voltage based on an image signal is supplied to the pixel electrode, and then, the pixel transistor is turned off so that a holding period during which the pixel electrode holds the voltage based on the image signal starts. A holding signal corresponding to change of the voltage based on the image signal in the pixel electrode in the holding period is supplied to the capacitor line so that a potential of the pixel electrode is constant.

摘要： An object is to provide a driving method of a liquid crystal display device with a low power consumption and a high image quality. A pixel includes a liquid crystal element and a transistor which controls supply of an image signal to the liquid crystal element. The transistor includes, in a channel formation region, a semiconductor which has a wider band gap than a silicon semiconductor and has a lower intrinsic carrier density than silicon, and has an extremely low off-state current. In inversion driving of pixels, image signals having opposite polarities are input to a pair of signal lines between which a pixel electrode is disposed. By employing such a structure, the quality of the displayed image can be increased even in the absence of a capacitor in the pixel.

摘要： To extend the range of distance (between a display screen and the eye of a viewer) with which the viewer can see 3D images with the naked eye and to reduce power consumption. A parallax barrier in a shutter panel is controlled to be arranged optimally in accordance with the distance between the viewer and a display panel. Specifically, an optimal parallax barrier is formed as appropriate by selectively switching a light-transmitting state and a light-shielding state of a plurality of optical shutter regions and a display element unit of pixels depending on a retention state. The retention state is realized in such a manner that at least one of electrodes between which a liquid crystal layer is sandwiched is connected to a transistor including a semiconductor layer containing an oxide semiconductor and the transistor is turned off.

摘要： In a pulse output circuit in a shift register, a power source line which is connected to a transistor in an output portion connected to a pulse output circuit at the next stage is set to a low-potential drive voltage, and a power source line which is connected to a transistor in an output portion connected to a scan signal line is set to a variable potential drive voltage. The variable potential drive voltage is the low-potential drive voltage in a normal mode, and can be either a high-potential drive voltage or the low-potential drive voltage in a bath mode. In the batch mode, display scan signals can be output to a plurality of scan signal lines at the same timing in a batch.

摘要： The occurrence of crosstalk in a display device which performs 3D display is suppressed. When 3D display is performed, part of a plurality of pixels perform desired color display and the other part of the plurality of pixels perform black display. Thus, as compared to the case where all of a plurality of pixels perform desired color display, the occurrence of crosstalk can be suppressed. A plurality of pixels which perform desired color display are changed depending on the display state. Therefore, as compared to the case where a plurality of pixels which perform desired color display are fixed when 3D display is performed, the display device can have a longer period until display change in a pixel becomes obvious (a longer lifetime) and variations in display among the plurality of pixels can be reduced.

摘要： To suppress fluctuation in the threshold voltage of a transistor, to reduce the number of connections of a display panel and a driver IC, to achieve reduction in power consumption of a display device, and to achieve increase in size and high definition of the display device. A gate electrode of a transistor which easily deteriorates is connected to a wiring to which a high potential is supplied through a first switching transistor and a wiring to which a low potential is supplied through a second switching transistor; a clock signal is input to a gate electrode of the first switching transistor; and an inverted clock signal is input to a gate electrode of the second switching transistor. Thus, the high potential and the low potential are alternately applied to the gate electrode of the transistor which easily deteriorates.

摘要： In a display device including a pixel in which a driving transistor and a light-emitting element connected to a source of the driving transistor are provided, a display defect is suppressed. Before a period in which the driving transistor supplies a current to the light-emitting element, a voltage which has substantially the same level as a voltage which is applied to one electrode and the other electrode of a capacitor is kept as a voltage between a gate and the source of the driving transistor in the period. Specifically, a node where the one electrode of the capacitor and the gate of the driving transistor are electrically connected to each other in the period is made in a floating state, and the other electrode of the capacitor and the source of the driving transistor are electrically connected to each other.
