摘要： Provided is a liquid crystal display device having a pixel including a transistor and a liquid crystal element and a protection circuit electrically connected to one of a source and a drain of the transistor through a data line.

In a moving image display mode, an image signal is input from the data line to the liquid crystal element through the transistor, and the first power supply potential is set at the first potential. In a still image display mode, supply of the image signal is stopped, and the first power supply potential is set at the second potential. The second potential is substantially the same as the minimum value of the image signal.

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.

摘要： It is an object to provide a liquid crystal display device and a driving method of a liquid crystal display device in each of which deterioration of an image display function can be suppressed and power consumption can be sufficiently reduced. In the liquid crystal display device, a fixed potential is input to a capacitor before a power source is turned off, so that a potential difference between electrodes of the capacitor disappears (capacitance becomes almost zero) such that electric field is not applied to liquid crystals, whereby the liquid crystals are in an initial state. When the supply of the power source is stopped after an initial-state image is displayed, unnecessary electric field is not continuously applied to the liquid crystals in an off state, whereby the liquid crystals can be in the stable initial state; therefore, the liquid crystals can be prevented from deteriorating.

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.
