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 of the present invention is to provide a liquid crystal display device which allows a desirable storage capacitor to be ensured in a pixel without decreasing the aperture ratio in response to changes in frame frequency. In a liquid crystal display device including a pixel transistor and two capacitive elements using an oxide semiconductor material in each pixel, one of the capacitive elements comprises a light-transmitting material to improve the aperture ratio of the pixel. Furthermore, through the use of characteristics of the light-transmitting capacitive element, the size of the storage capacitor in the pixel is varied by adjusting the voltage value of a capacitance value in response to the frame frequency varied depending on images displayed.

摘要： In a liquid crystal display device, amplitude voltage of an image signal written into a signal line can be decreased. A liquid crystal display device in which frame inversion driving is performed includes pixels each including a liquid crystal element and a transistor that controls voltage applied to a first electrode of the liquid crystal element. A scan line is electrically connected to gates of transistors in pixels in a corresponding row. A common line is electrically connected to second electrodes of liquid crystal elements in pixels in the corresponding row. In a first frame period, a first potential is sequentially supplied to the common lines in synchronization with sequential selection of the scan lines. In a second frame period adjacent to the first frame period, a second potential different from the first potential is sequentially supplied to the common lines in synchronization with sequential selection of the scan lines.

摘要： Objects are to provide a display device the power consumption of which is reduced, to provide a self-luminous display device the power consumption of which is reduced and which is capable of long-term use in a dark place. A circuit is formed using a thin film transistor in which a highly-purified oxide semiconductor is used and a pixel can keep a certain state (a state in which a video signal has been written). As a result, even in the case of displaying a still image, stable operation is easily performed. In addition, an operation interval of a driver circuit can be extended, which results in a reduction in power consumption of a display device. Moreover, a light-storing material is used in a pixel portion of a self-luminous display device to store light, whereby the display device can be used in a dark place for a long time.

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： A photolithography step and an etching step for forming an island-shaped semiconductor layer is omitted, and a liquid crystal display device is manufactured through the following four photolithography steps: a step for forming a gate electrode (including a wiring or the like formed from the same layer), a step for forming a source electrode and a drain electrode (including a wiring or the like formed from the same layer), a step for forming a contact hole (including removal of an insulating layer or the like in a region other than the contact hole), and a step for forming a pixel electrode (including a wiring or the like formed from the same layer). In the step of forming the contact hole, a groove portion in which the semiconductor layer is removed is formed, so that formation of parasitic channels is prevented.
